Detectives took Cedric Tinsley into custody last Saturday in Simi Valley. They say he was driving the victim's car.
Investigators say the alleged assault happened June 30 around 10 p.m. when the suspect entered an unsecured home on Astor Place in Northridge and sexually assaulted a woman, then fled with her car and property.
He's being held on $1.2 million bail.
Detectives are trying to determine if Tinsley is connected to any other unreported sexual assaults. They are asking anyone with information to contact detectives at (818)832-0609. Anonymous information can be provided to Crime Stoppers at (800)222-TIPS.
