Cruise was outside a movie theater in central London's Leicester Square on Sunday doing press interviews when a man squirted him with a water pistol disguised as a microphone, London's Metropolitan Police said.
Cruise initially appeared to laugh at the incident but then asked the prankster:
As the man gave a barely audible excuse, Cruise said: "Do you like thinking less of people, is that it?" The prankster tried to walk away but Cruise reached across the metal barrier, held his arm and said: "Don't run away. That's incredibly rude. I'm here giving you an interview and you do that ... it's incredibly rude."

Police detained the man who squirted Cruise and also arrested three other men who filmed the incident. The four were working on a new comedy show for British television station Channel 4 in which celebrities are the targets of practical jokes.
Police released the men on bail several hours later and ordered them to return to a central London police station Monday. When they returned three were re-bailed and a fourth held for further questioning, before being released later Monday.
Actress Katie Holmes, who recently got engaged to Cruise, was at the premiere but not by his side at the time of the incident.
