Ricky Gervais is furious after being attacked - with water bombs. The Office star was jogging past the UCL in London, England when a gang of students pelted him with the liquid-packed projectiles.

An eyewitness told The Sun newspaper: "It was really hot and some people were making water balloons. They shouted to him but he ignored them, so they chucked one at him to get his attention.

"They thought he'd see the joke but he marched up to the door and rang the bell."

Gervais - who recently starred in and wrote and episode of The Simpsons - said: "I wanted to check it wasn't some old woman emptying her chamber pot but all I found were some spotty students.

"I gave them a ticking off as a joke but they looked terrified so I felt guity afterwards."
