LONDON--A Polish man appeared in court Saturday charged with harassing British actress Keira Knightley, two days after being arrested outside a London theatre where the star is currently performing.

Marek Daniluk, 41, from north London, was arrested on Thursday outside the Comedy Theatre where Knightley, 24, has a part in Moliere's The Misanthrope.

Police arrested him on suspicion of harassment and he was charged on Friday, before his court appearance in central London on Saturday. His trial date was set for June 4.

Knightley, the star of the "Pirates of the Caribbean" franchise and "Pride and Prejudice", has previously complained of being harassed, claiming two years ago that she had five stalkers.
