Police say they have arrested a man prohibited from contacting Audrina Patridge outside the reality star’s Los Angeles home.

Los Angeles police Sgt. Kyle Kirkman says Zachary Loring was arrested Friday morning. Officers responded to “The Hills” star’s Hollywood Hills house after Loring was spotted knocking on her door.

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.
