Officers who deal with the problem of ever-increasing gang violence said Thursday they have run into something new and disturbing - a gang member who was apparently making bombs at his apartment.

Workers sent to clean a just-vacated apartment discovered the remnants of a makeshift bomb factory, and deputies later arrested the known gang member who had been evicted, seizing two pipe bombs and several weapons.Ronald D. Bennett, 23, was arrested Thursday at his mother's house, where deputies found two pipe bombs and four weapons, said Deputy Bill Wehner.

Bennett, who was arrested on suspicion of manufacturing explosive devices and was held in lieu of $60,000 bail, had been evicted from an apartment in Lawndale.

"The guy was operating a bomb factory, and it's safe to assume the bombs were going to be used in gang activities," Wehner said.

Wehner would not disclose exactly what materials were found in the Lawndale apartment, saying only "it was clear he was manufacturing explosive devices."

Officials said it was the first time they have discovered gang members producing bombs.
