Police have arrested a Queens man who tried to rape a woman before being scared off by the screams of a former Marine, cops said yesterday.

Kenneth King, 41, allegedly grabbed his 33-year-old intended victim from behind as she waited for her carpool in Whitestone at about 8:50 a.m. Wednesday, cops said.

Former Marine Brian Teichman, 31, who was dropping his 2-year-old daughter off at her baby-sitter, noticed the victim struggling, and screamed “Hey, get the f–k off of her!”

King was arrested yesterday at his Bayside home and charged with attempted rape and attempted sex abuse.
