Police Thursday sought the public's help in identifying a man suspected of committing a sexual battery against a woman on a bus in Northridge.

The battery occurred about 4:50 p.m. Tuesday on a bus that was en route from the intersection of Saticoy Street and Reseda Boulevard to the Cal State Northridge Transit Center, according to campus police.

"The suspect boarded the bus and sat next to the victim," according to a police statement. "During the commute the suspect extended his elbow up along the right side of her rib and breast. The suspect followed the victim off the bus and continued to loiter in the area near the victim."

The suspect was described as Asian, about 30 years old, 5 feet 4 inches tall with an average build and facial stubble. He was wearing glasses, a light blue T-shirt with white stripes on the shoulders and a white emblem on the left side of the chest, tan shorts and numerous bracelets on each wrist.

He also carried a dark-colored backpack.

Anyone with information about the suspect was urged to call the CSUN police investigations unit at 818-677-3826.
