The attorney for a now-fired Philadelphia police lieutenant charged with assault after being caught on video punching a woman at a festival says his client will be vindicated.

Jonathan Josey was charged Thursday with simple assault, a misdemeanor.

District Attorney Seth Williams says he made the decision after carefully reviewing the video. Williams says police were responding to a chaotic situation, but the use of force was unnecessary.

Defense attorney Fortunato Perri Jr. says Josey was working in a "very volatile environment" that day. He says the 19-year veteran will be vindicated and hopes to return to his job.

The video shows 39-year-old Aida Guzman being struck in the face and falling to the ground, her face bloodied, before being led away in handcuffs.
