Authorities responded to the 7000 block of E. Shorecrest Lane on Tuesday afternoon. The victim says she was jogging around the Walnut Canyon Reservoir when a man tried to talk to her.
Police say he knocked her to the ground and began punching and assaulting her, but she was able to escape.
When officers responded, she had several visible injuries as a result of the attack. The victim was able to give officers a detailed description of the suspect.
Officers quickly detained a man who was seen walking away from the entrance of the reservoir who matched her description.
After the victim positively identified the man, 55-year-old Mario Orlando Montano of Anaheim was arrested and booked on suspicion of sexual assault and felony assault. He is free after posting $50,000 bail.
Detectives believe Montano may have assaulted or attempted to assault other women in the area. Anyone with information is urged to call Orange County Crime Stoppers at (855) TIP-OCCS.
