? Police are questioning a man who they believe raped three women in Williamsburg.

Officers arrested Gerard Mitchell, 29, after the latest attack on a 38-year-old woman who was walking to work early Wednesday morning. Investigators say the suspect approached the victim from behind, threatened her with a weapon and took her to a secluded area where he sexually assaulted her.

Police say the suspect also robbed all three women; the first two attacks happened in October.
