Tom Cruise was dried with a towel after he was squirted with water

Four TV workers were arrested after the 42-year-old actor's face and jacket were drenched with water from a fake microphone on Sunday.

Channel 4 later apologised to Cruise for the stunt, which was filmed for a comedy show.

The four men were released on bail to return to a police station on 4 July.

Composure

They were arrested on suspicion of assault, but a spokeswoman for the Hollywood star confirmed he would not be pressing charges.

Cruise - who attended the premiere with his new fiancee Katie Holmes - was talking to journalists in Leicester Square when he was squirted with water.

The star struggled to maintain his composure, repeatedly asking one of the Channel 4 team: "Why would you do that?"

He said: "What's so funny about that? It's ridiculous. Do you like making less of people?

Cruise's fiancee Katie Holmes was also at the premiere

"I'm here giving you an interview, answering your questions and you do something nasty. You're a jerk."

The actor held the interviewer back and repeatedly called him "a jerk".

Security guards arrived and Cruise towelled himself down before signing more autographs for the 5,000 people who packed Leicester Square on one of the hottest days of the year.

He is famed for his lengthy walkabouts at film premieres, spending hours greeting fans, signing autographs and talking on their mobile phones.

A Channel 4 spokesman later said the incident was not intended to cause offence and was "very much in a spirit of fun".
