Peter Robbins, the voice of famous comic strip character Charlie Brown, was arrested on Sunday.

Robbins was driving a silver 2006 Mercedes-Benz C230 in San Diego around 8 p.m. when he was stopped by a border agent, according to the New York Post. Upon further examination, it was discovered that the 56-year-old voice actor had a warrant out for his arrest on charges that included making death threats and stalking.

U-T San Diego states that he was then arrested and charged with four felony counts of death threats and one felony count of stalking.

Robbins is being held on $550,000 bail.

Robbins is a child actor who began voicing Charlie Brown at the age of nine, and he has also acted in such television shows such as “F Troop,” “The Munsters” and “Get Smart.”

Charlie Brown is the protagonist in the comic strip “Peanuts” by Charles M. Schulz. He first appeared in comic strips in 1950 and has since become a popular household name.

Robbins provided the voice of Charlie Brown in the late 1960s, including the film “A Boy Named Charlie Brown” and the television specials “A Charlie Brown Christmas” and “It’s the Great Pumpkin, Charlie Brown.”

Robbins’ manager, Danielle Matthews, said on Tuesday that she had no comment regarding the arrest, but that she would comment on Wednesday.

Robbins is not the first voice actor to get in trouble with authorities. Back in November, Kevin Clash, the voice and puppeteer behind Elmo on “Sesame Street,” took a leave from the show after being accused of allegedly having  sexual relationships with underage boys.

Clash has since insisted the claims are false and the underage allegation is defamatory.

Clash is the third puppeteer to do the voice of Elmo since the character first emerged in 1979. Clash won numerous Emmy awards in his 28 years as Elmo's puppeteer.
