A woman was reportedly dragged into the back of a car in September and sexually assaulted at Fresno City College, according to the State Center Community College District Police Department.

Police say the woman was walking to her car in parking lot D at about 10:30 p.m. on a Wednesday in late September when the alleged sexual assault occurred. Parking lot D is near the Math/Science building and faces McKinley Avenue.

A man allegedly dragged her into the backseat of a silver 4-door Nissan Altima and sexually assaulted her.

The man is described as 6-foot-1-inch, 180 pounds, light-complected, Hispanic, in his 20s, brown hair and eyes, unshaven, and wearing a black t-shirt, dark jean and white tennis shoes.

Campus police were only made aware of the incident on Nov. 21, according to district spokeswoman Lucy Ruiz, and they are now investigating. The victim did not specify a certain date, making it difficult to find witnesses, Ruiz said.

Campus police said they will step up patrols during the next few weeks as the semester ends and the investigation continues.

Police escorts to the parking lots are available by calling 559-244-6140. Students and faculty should try to walk in groups to their cars, staying away from hidden doorways, shrubs and other areas where people can hide, police say.

Anyone who witnesses suspicious activity is also encouraged to call 559-244-6140 to report it.
