Detectives asked for the public's help Friday in identifying the man who sexually assaulted a woman walking in the Whittier Narrows recreation area in June.
Security cameras at a water facility recorded the man riding up to the woman on a trail, grabbing her, and dragging her into some bushes, where she was attacked.
A second camera recorded video of the man riding away on a bicycle.
"The guy is just a predator, he's a very dangerous individual, and that's why we need to identify him as soon as possible," said L.A. County Sheriff's Department Lt. Todd Deeds.
He said the attacker was Hispanic, in his mid 20s, 5-foot-9, about 175 pounds, with a teardrop tattoo under his left eye.
The circumstances of the assault do not match with any other recent incidents, he said.
