Police are looking for a man who they say assaulted a woman on a walking trail in Chino Hills earlier this week, officials said.

The crime, which was being investigated as an attempted murder of the 23-year-old victim, took place about 3 p.m. Wednesday on a trail near Rolling Ridge Drive and Hickory Lane, according to the San Bernardino County Sheriff’s Department.
“…the victim was violently attacked from behind while walking on trails,” the department said in a written statement. “The attacker was not known by the victim. The victim fought back, and the suspect fled on foot.”
Officials did not disclose whether the attack involved any weapons, or whether the victim suffered injuries.
Sheriff’s investigators described the attacker as a white man between 22 and 27 years old, of light complexion, between 5 feet 9 inches and 5 feet 10 inches tall. He was described as lean with defined muscles, although not “muscular” or “skinny.”
The man had buzzed, light brown hair and brown eyes, authorities said. He had acne scars on the upper portions of his face
He wore a black-and-gray gator-style face mask, a black long-sleeve shirt, black or dark blue jeans and black gloves with dark red stitching on the straps.
No further details were available Friday.
