LOS ANGELES — A 24-year-old doctoral candidate from China has been charged in connection with several gropings on the UCLA campus, authorities said today.

Pengcheng Bao was arrested Saturday at his Weyburn Terrace residence after an individual recognized him from a UCLA police flyer, said Phil Hampton of UCLA’s Media Relations unit.

Bao is a graduate student in chemistry and biochemistry. He is from Quinhuangdio, China.

Bao was booked on several counts of misdemeanor battery and one count of misdemeanor sexual battery. He is being held on $160,000 bail at Men’s Central Jail.

Bao was accused of grabbing several female students on their upper thighs when he passed them on sidewalks at several locations on the campus.

Students told police they had experienced several such incidents with Bao in the past.

One student took a photo of him with a smartphone, which was used in the police flier alert.

The investigation is continuing. Anyone wishing to report similar incidents were asked to call UCLA campus police at (310) 825-1491.
