Singer Scott Weiland is no longer part of the rock supergroup Velvet Revolver, according to a statement from the other members of the band yesterday. The brief statement referred to Weiland's "increasingly erratic" behavior as the cause for the split; Weiland has long battled heroin addiction and has been in and out of jail and rehab a number of times over the years.

Weiland has recently reunited with his old band, Stone Temple Pilots, and will undertake a summer tour. Tour dates will be announced next week.
