In the lawsuit, Cesar Sanchez-Guzman alleges that Singer offered to give him a tour of the yacht during a boat party near Seattle in 2003. Once cornered in a room, Singer allegedly forced the teen to perform oral sex before raping him, according to the lawsuit filed in Washington state court.

The lawsuit states that the yacht was owned by wealthy tech investor Lester Waters, and that the party was attended by a number of young gay men. Sanchez-Guzman states that he was 17 at the time of the party and did not know Singer except that he was a friend of Waters.

After the alleged assault, Sanchez-Guzman states in the lawsuit that Singer threatened to ruin his reputation if he came forward.
