Travell Wilson and Earnest Watkins, Jr. appeal from judgments of the district court 1 entered after a jury found them guilty of conspiracy to distribute cocaine and of aiding and abetting possession with the intent to distribute cocaine. We affirm.
As part of an ongoing investigation between the Drug Enforcement Administration and the Kansas City, Missouri Police Department, on June 23, 1993, in anticipation of executing a federal search warrant, law enforcement officers were conducting surveillance at the apartment of Kenneth Hulett. The officers saw Wilson and Watkins go into the apartment, and a short time later saw Wilson, who was carrying a black bag, and Watkins leave the apartment and get in a car. Officers followed the car and a chase ensued. Officers saw the car pull into a parking lot, and as the car slowed down, saw Wilson, who was carrying a black bag, get out of the car and run into a nearby wooded area. Watkins, who was the driver, was arrested after the car came to a stop. Wilson was arrested after officers found him lying face down in the wooded area. At the time of the arrest, officers could not locate the black bag they saw Wilson carry from the car into the woods. However, the next day officers returned to the area and found the bag, which contained 745 grams of cocaine. Both men were detained for about twenty hours and released pending future indictments. On March 29, 1995, a federal indictment charging Wilson and Watkins with conspiracy and aiding and abetting possession was returned. Wilson was arrested on April 21, 1995, and Watkins surrendered on May 4,1995.
Watkins filed a motion to dismiss based on pre-indictment delay. The court denied the motion. At trial, pursuant to a plea agreement, Hulett testified for the government. Among other things, Hulett testified that before the June 23 sale he had distributed cocaine to Watkins and Wilson on four occasions. In addition, the government introduced officers’ testimony, photographs, and the bag and the cocaine retrieved from the wooded area.
The jury convicted Wilson and Watkins of the drug offenses. The court sentenced Wil *971 son to 87 months imprisonment and Watkins to 97 months imprisonment.
WILSON
On appeal Wilson argues that the government’s alleged delayed production, or non-production, of transcripts of Hulett’s testimony in other criminal cases violated the omnibus trial order,
Brady v. Maryland,
Trial began on August 15, 1995. Before the jury was called in, Wilson complained to the court that the government had violated the omnibus order by either disclosing the requested transcripts late or not at all. Counsel, however, informed the court that he was able to obtain four of the requested transcripts from the clerk’s office. In response to the court’s inquiry regarding requested relief for the alleged violations, counsel “ask[ed] for a delay so we may go over these four additional transcripts ... in order to obtain proper impeachment material of witnesses at this trial.” The court told counsel he would be provided with “an opportunity to complete whatever it is you may not have completed” and an opportunity to make a record of his objections. After Hulett’s direct examination on August 16, the district court told counsel it would take a long recess to allow him to make a record regarding his discovery complaints. Counsel indicated an extended recess was agreeable. After the recess, without the presence of the jury, the court announced: “[Djefendants’ counsel in this case have agreed they have been given all the material that they asked for and they have no further requests as of noon today.” The court then stated: “So all these prior matters on this subject are mooted by this statement.” Counsel did not object and cross-examined Hulett. In this circumstance, it is clear that Wilson has failed to preserve the discovery issues for review.
See United States v. Warfield,
Even if Wilson had preserved the issues for review, his arguments are without merit.

As a general rule, we review discovery matters for an abuse of discretion.
United States v. Byrne,
Wilson’s
Brady
claim must also fail. “Where the prosecution delays disclosure of evidence, but the evidence is nonetheless disclosed during the trial,
Brady
is not violated.”
United States v. Gonzales,
Wilson next argues that the district court erred in admitting a coconspirator’s statement under Fed.R.Evid. 801(d)(2). The district court did not err. Indeed, the court followed
United States v. Bell,
Last, Wilson challenges the sufficiency of. the evidence, asserting that Hulett’s testimony was incredible. However, it was the jury’s function to assess Hulett’s credibility.
United States v. McCarthy,
WATKINS
Watkins argues that the district court erred in denying his motion to dismiss. Watkins alleges that the delay between his June 1993 arrest and March 1995 indictment violated the Speedy Trial Act, 18 U.S.C. § 3161(b), which provides that “[a]ny ... indictment charging an individual with the commission of an offense shall be filed within thirty days from the date on which such individual was arrested or served with a summons in connection with such charges.”' He also claims the delay violated the Sixth Amendment speedy trial guarantee. His statutory and constitutional claims are without merit. As to his statutory claim, his June 1993 arrest did not trigger the Speedy Trial Act clock. Under section 3161(b) “[t]he right to a speedy trial on a charge is triggered by arrest only where the arrest is the beginning of continuing restraints on defendant’s liberty imposed in connection with the formal charge on which the defendant is eventually tried.”
United States v. Stead,
*973
Watkins also argues that the district court erred in refusing to grant his request for a two-level minor participant reduction under U.S.S.G § 3B1.2(b).

On appeal, we review the district court’s denial for clear error,
United States v. Thompson,
Accordingly, the judgments of the district court are affirmed.
Notes
. The Honorable Scott 0. Wright, United States Senior District Judge for the Western District of Missouri.
. Among other trials, Hulett testified as a government witness in
United States v. Randolph,
. Wilson has filed a motion to supplement the record on appeal. To the extent Wilson seeks to supplement it with material filed in the district court, we grant the motion. We remind Wilson that "[m]ere speculation that a government file may contain
Brady
material is not sufficient to require a remand ..., much less reversal for a new trial."
United States v. Pou,
. The district court also rejected Watkins’ claim that the delay violated his Fifth Amendment due process rights. On appeal, he does not appear to raise a Fifth Amendment issue. In any event, the district court correctly rejected the claim. As the court held, Watkins had not proved that the delay had “actually and substantially prejudiced the presentation of [his] defense."
United States
*973
v.
Miller, 20
F.3d 926, 931 (8th Cir.),
cert. denied, -
U.S. -,
. At sentencing, Watkins only requested a two-level reduction for being a minor participant. We therefore need not address his arguments on appeal that he was entitled to a four- or three-level reduction under section 3B1.2. However, Watkins', arguments are without merit.
