Woody Harrelson punched a man who allegedly wouldn't stop taking photos of him and his daughter.
Police were called to the Watergate Hotel in Washington DC at around 11pm on Wednesday local time in response to a report about an assault on the roof deck, and found several people there, including the 60-year-old actor - who has Deni, 28, Zoe, 25, and Makani, 15, with wife Laura Louie - and one of his kids.
Police said a man, who appeared to be intoxicated, had taken photos of Harrelson and his daughter, and the "Hunger Games" star allegedly approached him and asked him to stop and delete the pictures he'd already taken.
A report by cops then tells how Harrelson admitted he got into a verbal dispute with the man who "lunged towards" him in an attempt to "grab his neck", and so he punched him "in his neck in defence of himself".
Witnesses backed up the "Three Billboards Outside Ebbing, Missouri" star's account of what had happened, and police told NBC Washington their statements suggested the other man had been the aggressor.
