A sexual assault suspect is behind bars after barricading himself inside a building at Paramount Studios in Hollywood late Sunday night. Authorities say the man was armed with a knife and became “uncooperative” when investigators with the Fullerton Police Department tried to arrest him. Multiple reports say there was an officer-involved shooting, but officials don’t believe the suspect was hit. The studio lot was evacuated and placed on lockdown as a result. The suspect was arrested without incident after being holed-up for around 90 minutes.
