Three weeks after [artist id="1006"]Pearl Jam[/artist] bassist Jeff Ament was mugged outside the Atlanta recording studio where the band are working on their new album, a surveillance video has surfaced of the incident.

[video id="391872"]The video shows Ament[/video] and a band employee, Mark Anthony Smith, being attacked last month by three men wearing masks and waving knives outside Southern Tracks Recording, a studio in North Atlanta favored by the band's longtime collaborator, producer Brendan O'Brien.

The DeKalb County Police Department reported that Ament and Smith were attacked by the men just before noon on April 27, when the assailants allegedly walked out of some nearby woods. The three men, brandishing knives, smashed windows on a rented Jeep Commander, stole a BlackBerry and other belongings and demanded money, according to the police report. They allegedly escaped with more than $7,300 worth of cash and belongings, including Ament's backpack, which contained his passport.

After the attack began, Ament is seen jumping from the passenger side of the Jeep and trying to flee, but is chased down by one of the suspects and knocked to the ground, suffering lacerations to the back of his head which were treated at the scene.

A police spokesperson told CNN they don't believe that Ament was specifically targeted, but that the alleged thieves were familiar with the studio because of its isolated location. Despite the surveillance footage, police have had a hard time identifying the attackers because of their masks. They reportedly were seen by witnesses fleeing the scene through the woods and jumping into a waiting Nissan Maxima. Anyone with information on the case is encouraged to call 770-724-7850.

A spokesperson for Pearl Jam had no comment on the incident.
