Police are seeking public assistance to locate a man who held a woman at knifepoint and sexually assaulted her in Pasadena over the weekend. 

It happened before 8:40 p.m. on Saturday, when officers were called to Sierra Villa Avenue and Foothill Boulevard regarding a report of sexual assault, according to a statement from the Pasadena Police Department. 

They learned that the suspect got into the victim's car and threatened her with a knife, forcing her to drive to another area where he sexually assaulted her, police said. 

At some point the victim was able to escape from the man and call 911.

By the time they arrived, however, he had already fled from the scene. 

Investigators describe the man, between 30 and 40 years old, as standing around 6-feet tall. He was last seen wearing a black face mask, a gray hooded rain jacket, light blue jeans and black shoes. 

"The suspect also has a distinctive raspy voice and is possibly a transient," police said.
