The defendant appeals from a conviction on a complaint charging attempted larceny of a motor vehicle. He contends that the complaint charging him with the crime was fatally defective and that the evidence *195 presented at trial was insufficient to support his conviction.
On October 7, 1978, Christina R. Fox parked her 1975 Ford LTD automobile in front of her home in Everett at about 12:00 p.m. The next morning she discovered that the automobile was missing from that location and she reported this to the Everett police. At about 8:00 p.m. of that same day two Boston police officers observed the defendant and another male in a 1975 Ford LTD which was parked on Summer Street in'the Charlestown district of Boston. As the officers drove up to the vehicle the two men attempted to duck down. The officers removed them from the automobile and then noticed that the automobile’s ignition switch had been "popped.” They also found a tool box and jumper cables in the vehicle. The defendant and his companion were then placed under arrest for attempted larceny of a motor vehicle. Fox later identified the automobile as the one taken from in front of her home, but she testified that the tool box and jumper cables did not belong to her.
The complaint charging the defendant with attempted larceny stated, in pertinent part, that the defendant Paul D. Burns, "did attempt to steal an automobile, to wit: a 1975 Ford L.T.D. of the property of Christina R. Fox, 18 Dunster Road, Everett, Massachusetts, but did fail in the perpetration of said attempted offence.” The defendant argues that the failure of the complaint to allege the commission of any overt act by him renders the complaint fatally defective. We agree.
A complaint must inform a defendant of the crime with which he is being charged and must provide him with information sufficient to enable him to prepare a defense.
Commonwealth
v.
Gill,
General Laws c. 274, § 6, provides that "[wjhoever attempts to commit a crime by doing any act toward its commission, but ... is intercepted or prevented in its perpetration, shall ... be punished.” The essence of the crime of attempt is that the defendant has taken a "step towards a criminal offense with specific intent to commit that particular crime.” Perkins, Criminal Law 552 (2d ed. 1969). It is not enough to allege that a defendant has formed the intent to commit a crime or that he has merely made preparations for the commission of a crime.
Commonwealth
v.
Peaslee,
The overt acts relied upon to support a charge of attempt must be alleged in the complaint charging the
*197
crime.
1
“The necessity that the overt acts should be alleged has been taken for granted in our practice and decisions.”
Commonwealth
v.
Peaslee,
In this case the complaint charging the defendant with attempted larceny of a motor vehicle made no reference to any overt act engaged in by the defendant. "The pleadings must be sufficiently definite not only to prevent the defendant from being put in jeopardy the second time but also to put him on notice of what he is charged with having done. In the instant case the accusation gives the defendant no notice of what he is charged with having done in making the attempt. The accusation seeks to charge him with an attempt to steal, and yet it contains no allegation whatever of the way in which the attempt was made.”
Wilburn
v.
State,
We do not think the defendant’s failure to request a bill of particulars precludes him from challenging the complaint. The purpose of a bill of particulars "is to give a defendant reasonable knowledge of the nature and character of the crime charged.”
Commonwealth
v.
Iannello,
*198
The bill of particulars will set out in detail that which is included in the allegations of an indictment.
Commonwealth
v.
Hayes,
The cases relied upon by the Commonwealth are distinguishable, as there was no contention in any of those cases that the indictments failed to allege an element of the crime charged which was necessary to sustain the conviction. Compare
Commonwealth
v.
Snell,
Deciding as we do, it is not necessary to reach the question whether there was sufficient evidence to support the conviction.
The judgment is reversed, the verdict is set aside, and the complaint is to be dismissed.
So ordered.
Notes
The complaint here was not phrased in the form suggested by G. L. c. 277, § 79 ("Schedule of Forms of Pleadings”). Nor can it be fairly said that the complaint tracked G. L. c. 274, § 6. See
Commonwealth
v.
Hare,
The Commonwealth is free to charge the defendant in a new complaint for attempted larceny (or larceny) of a motor vehicle because he could notJiave been convicted on the complaint in this case, and thus has not been in jeopardy of such a conviction.

Roby,
