WESTPORT - Westport police are investigating after a woman claims she was sexually assaulted at a home on Stony Brook Road.

The woman, who is from Fairfield, says she was at a bar with her sister and a friend when two men invited them to an after party.

The woman says she got in a car with the men while the other two women followed knowing only the street address, but not the town where they were going.

Police say the woman?s friend and sister got separated, but aren't sure if the men intentionally tried ditch the other women who apparently thought they were going to Fairfield.

The victim?s sister called police to the address she was given. The victim initially denied anything happened, but later told a female officer she had been assaulted.

Police say they are looking for a person of interest in the case.
