Navid Farsi, 28, was arrested on suspicion of battery after throwing a bag of powdered sugar at the Maroon 5 star as he greeted fans on Hollywood Boulevard following a performance on the show.

Farsi is being held on $100,000 (£67,000) bail.

He was tackled to the ground by security guards immediately after his attack on Levine and apprehended until police officers arrived and arrested him.
