Did Sean Penn Pop a Pap?

Sounds like Sean Penn’s notorious temper has reared its violent head once again.

E! Online reports that paparazzi agency Flynet Pictures is accusing the Milk actor of physically attacking one of its lensmen.

According to the agency, Penn “emerged from his truck and walked over 50 feet towards the photog and kicked and punched him without provocation…Penn also berated the photog with obscenities and shouted that he would ‘put you in a box’ to the photog before going back to his house.”

Flynet claims that, as a result of the alleged assault, their photographer “suffered multiple cuts and bruises from the attack, has filed a police report and is considering pressing charges for battery.”
