TV presenter Ant McPartlin and his mother Christine were attacked during a pub dinner in London last week.
The co-host of Saturday Night Giveaway was with his 58-year-old mum and his aunt when a group of youths started banging on the pub window and began making crude gestures and filming them on their phones.
According to The Sun, McPartlin went outside to ask them to stop but the group grabbed him and put him in a headlock. When Christine ran out to help her son, she was pushed to the ground.
A witness told The Sun: “The youths were banging on the window, filming them and generally being a pain - and they just wouldn’t let it lie.
“Ant was completely reasonable and said, ‘Leave it out, lads, I’m just having a quiet meal.’ But it immediately turned really nasty and one of them jumped on him and put him in a headlock.
“When his mum came out to see what was going on she was pushed over. It was shocking and terrifying to see. Ant was furious and both he and his mum were left shaken.
A spokesman for Scotland Yard said: “At 8.13pm on Thursday March 13 there were reports of an assault in Spencer Road, Chiswick. Police attended but no allegation was made and no one suffered any notable injuries.”
