A National City resident and registered sex offender has been arrested for downloading dozens of child pornography on a library computer, somehow circumventing a filter for websites like that, National City Police Department (NCPD) officers said.
Library personnel called police when they learned a man, identified as Julio Martinez, was downloading child pornography at one of the library computers, police said. A monitoring system alerted the security guard on shift that someone was viewing porn, said NCPD Lt. Alex Hernandez.
Martinez somehow got around a filter blocking such websites at the library, Hernandez said.
"They do (have a filtering system)," Hernandez said. "And that's one of the thing we're looking at right now."
Officers arrested Martinez, 37, for possession of child pornography on Saturday. He was in possession of more than 100 movies, police said, and had storage devices like thumb drives and a hard drive with him. Police are investigating to determine whether he had child pornography on those devices.
Martinez admitted to trading the movies with other people, police said.
Police seized the library computer as evidence.
