(NBC NEWS) -- A clerical error caused Los Angeles County sheriff's deputies to release a jail inmate charged with gang-related murder last month, and authorities have asked the public to help them find him.
Johnny Mata, 32, was released in downtown Los Angeles on April 4 after he was charged with a 2010 gang murder in Baldwin Heights, according to a Los Angeles County Sheriff's Department statement.
"Mata's release should not have occurred because a murder charge had been filed by the District Attorney and a processing clerk had not yet entered it as a 'hold' on inmate Mata," the statement said.
Mata was arrested May 25, 2012 by the El Monte Police Department. His last court date was listed as April 3 -- the day before his accidental release.
Mata was described as a Latino man, 6 feet, 1 inch tall, 197 pounds.
