Hollywood actor-comedian Robin Williams was pulled over by the police for riding his bicycle on a New York sidewalk.
The 59-year-old actor, who is currently starring in Broadway's Bengal Tiger at the Bahgdad Zoo, said he was dressed as a "terrorist or a crack dealer" at the time, reported Los Angeles Times.
Speaking on US show The View, Williams said he was cycling down the sidewalk on a one-speed track bike when he suddenly heard a "whoop, whoop" and someone shout "pull over".
Once Williams pulled down the mask, officers checked his identification and let him go with a warning.
The Good Will Hunting star is currently sporting a large bushy grey beard for his appearance in the Broadway play.
Williams has received rave reviews for his performance in the production, which follows the story of two American Marines and an Iraqi translator whose lives are changed forever after an encounter with a quick-witted tiger.
The actor recently completed work on the forthcoming Happy Feet 2 in 3D, which hits cinemas on November 18. The actor voices the character of 'Ramon', with Elijah Wood and Pink also lending their voices to the project.
