Peter Robbins, the voice of Charlie Brown in the 60's, is curently sitting in the San Diego County Jail, charged with 12 felony counts of making criminal threats and stalking, authorities said.

Border Patrol agents arrested Robbins late Sunday as he entered the United States from Mexico at the San Ysidro, California, port of entry, according to a U.S. Customs and Border Protection spokesman.

Robbins was 9 in 1965 when he was cast as Charlie Brown in the animated "A Boy Named Charlie Brown." "A Charlie Brown Christmas" was produced later that year, using Robbins as the lead voice. Other TV movies using Robbins' voice include "Charlie Brown's All Stars!" "It's the Great Pumpkin, Charlie Brown," "You're in Love, Charlie Brown" and "He's Your Dog, Charlie Brown." His last role as Charlie Brown -- "It Was a Short Summer, Charlie Brown" -- was produced when Robbins was 13.
