Appellant, Bradley Raymond Neumann, was indicted for possessing heroin and dem-erol with intent to deliver in violation of 21 U.S.C. § 841(a)(1). After a jury trial, he was acquitted of these offenses but was convicted of the lesser included offenses of possessing these substances in violation of 21 U.S.C. § 844. The district court 1 sentenced him to a one-year term of imprisonment for having possessed each drug with the two sentences to run concurrently. Neumann appeals alleging his warrantless arrest was made without probable cause and that the warrantless post-arrest search of his automobile was improper. We affirm.
I.
The facts are essentially undisputed.
On November 3, 1977 Bradley Neumann and his wife, Sandy, were stopped by police officers, taken from their automobile and arrested shortly after leaving a Minneapolis duplex. This duplex had been placed under surveillance by local police and federal drug enforcement officers earlier that day because an officer had made purchases of heroin and demerol from Ms. Roberta Davis who had taken him to the duplex on three separate occasions to obtain the purchased drugs. Ms. Davis had identified her source as “Sandy,” a woman later identified as Ms. Neumann.
On the afternoon of the Neumanns’ arrest, Minneapolis police officer Strauss and an informant named Rassmusen went to the duplex to attempt another purchase. Rassmusen had participated in the earlier transactions with Ms. Davis and now sought to make an independent purchase from her source. Strauss remained in his automobile *357 while Rassmusen entered the dwelling. He returned in about ten minutes and reported witnessing a woman named Sandy bagging what be believed to be an ounce of heroin. He also told of watching a man named Brad preparing heroin for injection and of seeing “a box of pills in there.” He had agreed to purchase a quarter ounce of heroin from Sandy and had returned to the car to obtain the purchase money. The sellers were, of course, the Neumanns.
Strauss gave one hundred dollars to Rass-musen for a down payment on the heroin until he could obtain the balance of the seven hundred dollar purchase price. Rass-musen again entered the duplex and upon returning reported that Sandy had “become nervous” upon receiving the money. The two men then left the area for about fifteen minutes to obtain the additional six hundred dollars.
When they returned, Rassmusen entered the duplex with the money. As he went in the front door, the Neumanns left through the rear door and drove away in their automobile. Officer Strauss observed two persons leaving the building,’ and took down a description of their vehicle. One of the individuals was carrying a cardboard box. Rassmusen learned of the Neumanns’ departure from the owner of the duplex, Vickie Dowdie, who told him that they had taken a quantity of drugs with them because they had become “paranoid.” She also alleged that the Neumanns had stolen some heroin from her.
With this information Rassmusen returned to Strauss who radioed a surveillance vehicle and instructed the officers to stop and arrest the Neumanns. Rassmusen then proceeded to purchase heroin from Ms. Dowdie.
The Neumann car was stopped a few minutes later by several police officers. Both of the Neumanns were quickly removed from the car and arrested. As Sandy Neumann stepped out of the car, she dropped a small packet of heroin on the ground. Three more packets were found in her mouth, and a fifth was later discovered in the rear of a police car used to transport her to the police station.
After both of the Neumanns were removed from their car and handcuffed, the arresting officers conducted a search of the vehicle. The lid was removed from a closed Dayton’s Department Store box which was sitting on the floor of the driver’s side; and the officers discovered that it contained numerous baggies of pills, some of which were later identified as demerol. The lid of the box was replaced, and the car was then driven to the Minneapolis police garage for a full inventory search.
The arresting officers had not obtained either an arrest or a search warrant prior to stopping the Neumann vehicle, nor was one obtained before conducting the inventory search at the police garage.
II.
Appellant Neumann first asserts that his warrantless arrest was made without probable cause. This contention is without merit.
Probable cause for a warrantless arrest hinges upon
[w]hether, at the moment the arrest was made, . . . the facts and circumstances within [the arresting officers’] knowledge and of which they had reasonably trustworthy information were sufficient to warrant a prudent man in believing that [the suspect] had committed or was committing an offense.
Beck v. Ohio,
In determining whether probable cause existed, we look to the “objective facts available for consideration by the agencies or officers participating in the arrest,”
i. e.,
the collective knowledge of the arresting officers.
United States v. Stratton,
To form an adequate basis for a finding of probable cause, an informant’s hearsay *358 tip must reveal (1) some of the underlying circumstances from which the informant concluded that the narcotics were located where he claimed they were, and (2) some of the underlying circumstances from which the officer concluded that the informant was credible and his information reliable.
United States v. Regan,
Neumann’s argument here is that neither prong of Regan was met in this case because Officer Strauss’ information concerning the whereabouts of the allegedly missing heroin did not come from Rassmusen, an informant of unquestioned reliability, but instead from the uncorroborated statements of Vickie Dowdie, a drug dealer with no previous history of reliability. The facts belie this assertion.
We have stated that it is the cumulative effect of the evidence at the time of the arrest which determines probable cause.
United States v. Peep,
III.
Appellant’s second and final contention is that the warrantless, post-arrest search of the department store box found in his car violated his fourth amendment right to be free from unreasonable searches and seizures. He relies primarily on the Supreme Court’s opinion in
United States v. Chadwick,
[b]y placing personal effects inside a double-locked footlocker, [the defendants] manifested an expectation that the contents would remain free from public examination. . . . There being no exigency, it was unreasonable for the Government to conduct this search without the safeguards a judicial warrant provides.
*359
United States v. Chadwick, supra,
Recent cases in this circuit have considered and applied the holding in
Chadwick.
In
United States v. Schleis,
A similar result was reached in
United States v. Stevie,
No. 77-1335,
As the above cases demonstrate, our task here is a familiar one. We must review the facts before us to determine whether
this
warrantless search was justified under one of the narrow, well-defined exceptions to the search warrant requirement, keeping in mind the limitations placed on these exceptions by the Supreme Court in
Chadwick.
Such searches are presumptively invalid, and the burden is on the government to establish the existence of circumstances making the warrantless search imperative.
Coolidge
v.
New Hampshire,
We first note that the search in this case cannot be justified as incident to a valid arrest. In order to come within this exception,
Chadwick establishes that the critical factor is the extent to which the property is within the control of the law enforcement officers, rather than the amount of time or space between the arrest and the search. Once the officers obtain exclusive control, the requirement for a warrant under Chadwick is triggered. Ordinarily, the initial seizure at the time of arrest would be sufficient to place the property within the officers’ exclusive control.
United States v. Schleis, supra,
*360 Here the search of the closed box was made after the Neumanns were removed from their car and handcuffed. There was no longer any danger that either of them could obtain a weapon from the box or destroy any evidence contained in it. Moreover, there was no reason for the officers to suspect the box contained explosives or other dangerous instrumentalities.
A more difficult problem is posed by the government’s contention that the search was justified under the automobile exception to the warrant requirement. The Supreme Court in Chadwick expressly recognized the continued viability of this exception.
[Tjhis Court has recognized significant differences between motor vehicles and other property which permit warrantless searches of automobiles in circumstances in which warrantless searches would not be reasonable in other contexts.
Our treatment of automobiles has been based in part on their inherent mobility, which often makes obtaining a judicial warrant impracticable. Nevertheless, we have also sustained ‘warrantless searches of vehicles ... in cases in which the possibilities of the vehicle’s being removed or evidence in it destroyed were remote, if not non-existent.’
The answer lies in the diminished expectation of privacy which surrounds the automobile:
‘One has a lesser expectation of privacy in a motor vehicle because its function is transportation and it seldom serves as one’s residence or as the repository of personal effects. . It travels public thoroughfares where both its occupants and its contents are in plain view.’
United States v. Chadwick, supra,
In Stevie, however, this court held that while in that case officers were authorized to seize suitcases from the rear of the arres-tees’ station wagon, they were not authorized to open and search those suitcases without a warrant. We said in part:
The Court in Chadwick clearly held that an individual has a legitimate expectation of privacy in the contents of luggage. Every factor which the Court cites in support of its holding remains present whether the luggage is inside or outside an automobile.
United States v. Stevie, supra,
We thus rejected the position taken by the Ninth Circuit in
United States v. Finnegan,
Yet the
Stevie
case does not provide a solution to the problem now before this court. We intimated there that we might agree with the result in two other companion Ninth Circuit cases,
United States
v.
Ficklin
(and
United States v.
Seefeldt),
This court is of the opinion that the warrant requirement in Chadwick should not be extended to the facts of this case. There is simply an insufficient expectation of privacy in an unsecured cardboard box sitting in plain view in the passenger compartment of an automobile. The arresting officers *361 merely lifted the lid of the box and discovered a large quantity of pills. Unlike the situation in Stevie, where the officers could have seized and inventoried the locked suitcase as a unit without fear of loss or theft of the contents, here it was reasonable for the officers to promptly examine the contents of the box and later to have the drugs properly inventoried and secured. This procedure protected the legitimate interests of the arresting officers, including protection against unwarranted allegations of theft or loss, and could well have protected the interests of the Neumanns in having their property properly identified, safely kept and returned had not the box contained a controlled substance.
Further, the officers had probable cause to believe the box contained illicit drugs. Ms. Davis had admitted obtaining both heroin and demerol capsules from “Sandy.” Rassmusen had reported seeing a box of pills in the duplex after his first visit. Ms. Dowdie told him shortly thereafter that the Neumanns had left the duplex with drugs in their possession. And Officer Strauss watched them get in their ear with a box and drive away. The search of both the box and car was thus fully justified under the automobile exception.
