Sean Penn's violent clash with a paparazzo last October (09) has landed him in more trouble - the Oscar winner is facing a lawsuit from the snapper after he allegedly threatened to kill him.
The actor has already been charged with two misdemeanour counts of criminal battery and vandalism after reportedly kicking photographer Jordan Dawes and damaging his camera in a bust-up in California.
Dawes claims he suffered serious injuries after Penn started "kicking and punching" him, leaving him in need of surgery on his knee.
According to legal papers filed in Los Angeles County Superior Court, Dawes accuses Penn of breaking his camera before threatening his life by sneering, "The next time I see you, you will be in a box."
Dawes is seeking compensation for the alleged attack.
Penn's criminal case is still pending, reports TMZ.com.
