Actress Audrina Patridge arrives at the 'Los Premios MTV 2009' Latin America Awards held at Gibson Amphitheatre on October 15, 2009 in Universal City, California.
Kirkman says Loring was arrested on suspicion of stalking and violating a court order. Jail records show he is being held on $150,000 bail.
Patridge obtained a three-year restraining order against Loring in September. She testified at the time that she was afraid after the 24-year-old repeatedly came to her house and gave her disturbing drawings.
The arrest was first reported by celebrity Web site TMZ.
