On March 21, 1968, the defendant was indicted for receiving ‘ a motor vehicle knowing the same to have been stolen, in violation of the Dyer Act, 18 U.S.C. § 2313 (1964). On the same date one Aristomenis Theodore, to whom defendant refers as his “co-defendant” was indicted on a similar charge. A week later the defendant pleaded not guilty and his case was assigned for trial to May 23. On that day the defendant, through his court-appointed attorney, informed the court that he wished to change his plea to guilty. After complying with all the requirements of Fed.R.Crim.P. 11, the court accepted the defendant’s change of plea and on June 7 he was sentenced to imprisonment for two years. Because he was then serving another sentence in a state prison, defendant did not begin *592 to serve this sentence until August 5, 1969.
On March 4, 1970, defendant brought the instant “Motion to Vacate Sentence” alleging “that he and his co-defendаnt pleaded guilty on said charges after being promised a suspended sentence * * * by Louis M. J'anelle, Esq., the United States Attorney.” In his brief defendant states that this promise was his solе reason for pleading guilty; that he and his “co-defendant” were given the same proposition at the same time; that the co-defendant was granted relief and that he is entitled to equal treatment. The district court denied defendant’s motion without a hearing.
Although the motion comes too late for Fed.R.Crim.P. 35, it can be treated as a cоllateral attack upon his sentence under 28 U.S.C. § 2255 (1964). The government contends that the defendant is not entitled to a hearing because his allegations are conelusory and lack specificity. Macon v. United States,
The Supreme Court has held that “A guilty plea, if induced by promises or threats which deprive it of the character of a voluntary act, is void.” Machibroda v. United States,
supra
at 493,
The government argues that, because defendant had the benefit of a cоmplete Rule 11 inquiry at which he stated, among other things, that he had received no promise in return for his guilty plea, the district court was entitled to dispose of his motion on the basis of “the files
*593
and records of the case.”

But as in
Machibroda,,
“the factual allegations contained in petitioner’s motion and affidavit * * * related primarily to purported occurrences outside the courtrоom and upon which the record could, therefore, cast no real light.” Machibroda v. United States,
supra
at 494-495,
We note that defendant is not attempting to withdraw his guilty plea but is only challenging the validity of his sentence. At one time, the Fourth Circuit took the position that a petitioner must establish the invalidity of his plea before his sentence could be vacated. Pilkington v. United States,
Defendant contends that he will suffer unfair discrimination if he is not accorded the same treatment as his co-defendant Theodore. On remаnd, Theodore’s sentence was suspended by the district court on the ground that his guilty plea had been induced by an unfulfilled promise by the United States Attorney. We note, however, thаt Theodore offered very compelling evidence at his hearing. He in *594 trodueed a letter which the United States Attorney had sent to his lawyer promising to recommend а suspended sentence. We do not know as yet what evidence this defendant will offer.
Accordingly, we conclude that the defendant is entitled to an evidentiary hearing. We do not determine whether it is necessary that defendant be present at the hearing. That is discretionary with the district court.

Machibroda v. United States,
supra
at 495-496,
Reversed and remanded to the district court for рroceedings consistent with this opinion.
Notes
. There is some suggestion in a subsequent Second Circuit case that an unfulfilled prosecution promise can be the basis for vacating a guilty plea only if the prosecution did not
intend
to honor its promise. United States ex rel. Wissenfeld v. Wilkins,
. 28 U.S.C. § 2255 (1964) provides:
“ * * * Unless the motion and the files and records of the case conclusively show that the prisoner is entitled to no relief, the court shall * * * grant a prompt hearing thereon, * * * ”
. As defendant notes in his brief, the government’s argument suggests that, in reply to the court’s inquiry about inducements, defendant would be expected to respond: “Yes, your honor, I have been promised a deal by my attorney and he tells me that the United States Attorney has agreed to the deal and that you sir, have been previously informed of the agreements set forth in said deal.”
. 28 U.S.C. § 2255 (1964) provides:
“ * * * A court may entertain and determine such motion without requiring the production of the prisoner at the hearing.”
