A backup musician with the Smashing Pumpkins died from an apparent overdose Friday after injecting heroin with the group's drummer. The drummer was arrested on a misdemeanor drug possession charge, police said.

A visibly wobbly Jimmy Chamberlin, 32, was released after being given a summons. He was ordered to appear in court Aug. 13.Earlier, the other band members - front man Billy Corgan, guitarist James Iha and bassist D'Arcy - also were questioned, but not charged. They, like Chamberlin, left a police station without speaking to reporters.

No other arrests were expected, said police spokesman Mike Collins.

The overdose victim, 34-year-old Jonathan Melvoin, was a veteran keyboard player hired for the current tour of the Smashing Pumpkins, one of the top acts on the alternative rock scene.

The group was in town for two sold-out concerts at Madison Square Garden and a show at New Jersey's Meadowlands. Those shows and nine other July concerts scheduled in other cities were postponed.

The band's publicist released a brief statement expressing "great sadness" over Melvoin's death. "Our thoughts and heartfelt condolences go out to his wife and family," the statement said.

Police said Chamberlin and Melvoin began shooting heroin together at about 11 p.m. at the Regency Hotel, where rooms cost more than $200 a night.
