Police are investigating a sexual assault on the Arroyo Trail in Livermore on Tuesday evening, an area that has seen at least three similar attacks in recent years, authorities said.

Around 6 p.m., the victim, a 29-year-old Livermore woman, told police she had been walking on the trail near Arroyo Road when a man approached from behind and grabbed her. The man sexually assaulted the victim before fleeing the area, police said.

The attacker was described as being in his early to mid-30s, standing 5 feet 10 inches to 6 feet tall, weighing between 180 and 190 pounds, with dark eyebrows and dark, unshaven facial hair. He was wearing a dark, long-sleeved, hooded sweatshirt and baggy, dark sweatpants, police said.

The victim described the man as being dirty and scruffy in appearance, police said.

In May 2013, and again last May and August, three separate incidents of sexual assault occurred in the same area, police said. In each case the women were approached by men who grabbed them and sexually assaulted them before running off.

Police did not say if any of those cases were related to Tuesday’s attack, but said they would be beefing up patrols in the area.

Investigators encouraged anyone who witnessed this incident, or has any information about the attack, to call the Livermore Police Department at (925) 371-4777
