CHULA VISTA (CBS 8) - A string of groping attacks on women in Chula Vista has many people on edge. In response, a member of the Xtreme Justice League has arrived -- in costume -- to help police track down the groper and fight crime.

Mister Xtreme is a costumed crime fighter waging a war on a serial sexual assault suspect who has been terrorizing defenseless Chula Vista women for the past four months.

"You're a low-life, you're a coward and nothing but scum. I would do the smart thing and turn yourself in," he said.

The suspect strikes at all times of day and night and runs away after each incident. Victims who have ranged in age from 15 to 40 years old describe the attacker as a light-skinned Hispanic or white man in his early 20s with a medium build and thin mustache.

For several hours, Mr. Xtreme passed out flyers to dozens of people at Fourth and J Thursday to help spread the word about the serial groper.

The crime spree has mainly focused in and around the city's Broadway corridor from F Street to East Palomar Avenue, about a four- to five-mile long stretch. Nervous residents say they welcome the extra protection.

"I think it's a good idea to have someone out here, you know, on the streets, on the lookout, not only for this suspect, but for other people that are doing illegal stuff," resident Lupe Ruiz said.

Mister Xtreme and other members of his team will be patrolling Chula Vista every week to find the suspect so violence against any more women will stop. He has a message for the man who has been on the prowl since last September, striking fear in the community.

"You can run, but you can't hide… this is not the NFL but the XJL," Mr. Xtreme said.
