MADISON (WKOW) -- A Madison man accused of sexually assaulting a woman with disabilities is now charged.
Tremaine Williams, 35, appeared in court for the first time on Tuesday where he was charged with two counts of second degree sexual assault and two counts of third degree sexual assault.
Investigators say he forced a stranger to touch him while they were riding a Madison Metro bus on January 9.
Police say the incident was reported when the bus arrived at the East Transfer Point.
According to court documents, bus security video shows Williams started talking with the victim, then he touched himself and forced her to touch him.
A court commisssioner decided on a $10,000 cash bail, based on the charges and the investigation.
"If what the state says in the complaint is accurate, they have pretty good evidence to support those allegations and would appear fairly readily provable," said Commissioner Jason Hanson.
Police say the woman, who has disabilities, reported the incident to someone else on the bus, who then contacted police. Williams was arrested the next day.
Williams could face additional penalties for these four charges of sexual assault, because he was convicted in 2017 of exposing himself in public and has other misdemeanor convictions for theft.
