Authorities on Tuesday asked for the public’s help in identifying a man suspected of a sexual assault reported earlier this month in the city of Industry.

The assault occurred in the morning hours of Dec. 10 in the 1600 block of Azusa Avenue at Colima Road, according to the Los Angeles County Sheriff’s Department.

The suspect was described as a transient white man in his 30s with black hair. He was last seen wearing a dark jacket and gray sweatpants and is believed to have visited the Covina and La Puente areas, according to sheriff’s officials.

Investigators said he was last seen riding a Foothill Transit bus in those communities, prompting the release of a surveillance image in hopes of identifying him.

Details of the alleged assault were not immediately released as the investigation remained ongoing Tuesday afternoon.

“The Los Angeles County Sheriff’s Department-Special Victims Bureau is tasked with investigating the sexual and physical abuse of children and felonious sexual assaults involving adult victims,” according to the sheriff’s department.

Anyone with information about the suspect or the assault was urged to call the LASD Special Victims Bureau at 877-710-5273 or email specialvictimsbureau@lasd.org. Tipsters who prefer to remain anonymous can call Crime Stoppers at 800-222-8477 or visit lacrimestoppers.org.
