Three members of the Brooklyn indie band The Yellow Dogs were shot and killed by an ex-bandmate last night in East Williamsburg, NBC New York is reporting. The shooter, who also took his own life, was allegedly kicked out of the band a year ago for selling equipment. A fourth band member was shot twice and injured but is expected to live.

Law enforcement officials said the surviving victim, 22, called 911 shortly after midnight and reported the shooting. Responding officers found the three dead victims on the second and third floors of one apartment. The body of the gunman was found on the roof of the building, and the .308-caliber assault rifle authorities believe he used to shoot his former bandmates was found next to his body.

The Yellow Dogs are a post-punk group from Tehran who recently relocated to the United States. The band appeared at SXSW and were also featured in the 2010 film No One Knows About Persian Cats.

UPDATE: Publicist for The Yellow Dogs released this statement, saying that the shooter was not a former member of the band:

“[Akhbar] was in another band from Iran and the two groups were acquaintances in the past. A personal conflict between the guys resulted in the dissolution of their relationship in 2012. The shooting resulted in the death of two of the members of the Yellow Dogs, Sourosh Farazmand (guitarist) and Arash Farazmand (drummer), along with a friend of theirs, fellow musician and author Ali Eskandarian. The shooter died from a self inflicted bullet wound on site.”
