*940 Opinion
Petitioner and defendant Norman Walker, Jr., was charged in one information with possession of a concealable firearm by an ex-felon (count I, Pen. Code, § 12021) and armed robbery (count II, Pen. Code, § 211). The information also alleged that defendant had been convicted of “robbery and narcotics violations” on July 20, 1967, and June 25, 1968. After being held to answer at the preliminary hearing, defendant made a motion to sever the two counts; the motion was denied. This petition which we treat as praying for a writ of mandate followed. We stayed the trial and granted an alternative writ.
Facts
On April 2, 1973, a robbery occurred at the Western Federal Savings and Loan Association in Inglewood. The victims identified the robbers as three male Negroes with pistols and one rifle, all wearing knit caps. A cashier found an envelope near her cash drawer after the robbery; she had not seen the envelope before the robbery. One of the robbers, at the far side of the office, had had an envelope of “some sort” over his face. There were seven fingerprints on the front of the envelope, five of which were identified as belonging to defendant. Another two fingerprints belonged to another, unidentified person.
On July 17—106 days after the robbery—defendant was arrested at an address where four other persons were also detained. These persons were in the living room; defendant was in the bedroom. A police officer saw a .38 caliber revolver in a jacket pocket in an open closet, apparently in the same room where defendant was arrested. When defendant was booked, he gave two addresses; one was the location where he was arrested.
Discussion
Penal Code section 954 provides that an information “may charge two or more different offenses connected together in their commission, . . . under separate counts, . . . provided, that the court ... in the interests of justice and for good cause shown, may in its discretion order that the different offenses ... be tried separately. ...”
Defendant contends that the trial court abused its discretion in refusing to grant his motion to sever, first, because there is no connection between the robbery and the weapon charges, and, second, even assuming some connection, joinder of the two counts will severely prejudice him.
The relevant factual and legal circumstances of the charged crimes are *941 as follows: First, defendant was not identified by anyone as the robber; he was linked to the crime by the fingerprints picked off the envelope found in the bank. Second, the only evidence of weapons was that the robbers had “pistols and one rifle . . . .” No further identification of the weapons is disclosed. Third, a .38 caliber revolver was discovered 106 days later when defendant was arrested. Fourth, when defendant was arrested, there were five people in the apartment; four in the living room, and defendant in the bedroom, where the weapon was apparently found. Fifth, proof of the illegal weapons possession charge requires proof that defendant is an ex-felon.
Joinder of different offenses is permissible “even though they do not relate to the same transaction or event, if there is a common element of substantial importance in their commission, for the joinder prevents
repetition
of evidence and saves time and expense to the state as well as to the defendant.”

“Where an accusatory pleading charges separate offenses each involving the use of the same gun in their commission, the joinder has been held to be proper under section 954.”

We need not, however, decide whether this statement of the rule is too broad. (Cf.

People
v.
Scott, supra,
In this case, defendant has, on the record before us, made no admissions, and is tied into both crimes only by circumstantial evidence.
*943 In conclusion, where two dissimilar offenses occur a significant period of time apart, are connected only by an otherwise unidentified weapon, and proof of one charge involves potentially prejudicial and otherwise inadmissible evidence on the second charge, the refusal to grant a motion to sever the charges is an abuse of discretion.
The alternative writ is discharged. The peremptory writ is granted.
Stephens, J., and Ashby, J., concurred.
Notes
The danger of a miscarriage of justice lies in the real possibility that, in spite of correct instructions, the felony conviction, irrelevant to the robbery count, will negate any reasonable doubt of defendant’s guilt of robbery; that he will be convicted “on principle.” This type of danger was recognized in
