One of Johnny Depp's bodyguards has been accused of injuring a woman at an Iggy Pop concert after she strayed too close to the actor, according to a report.

Robyn Ecker, 52, has filed a police report alleging she was tackled to the ground by a security guard who was looking after the star during the gig at Los Angeles' Palladium on Thursday night, according to TMZ.com.

Ecker claims the unnamed bodyguard grabbed her wrists and forced her to the ground after she accidentally got too close to the star, who was seated beside her.

She was subsequently admitted to hospital to treat her alleged injuries and filed a police report about the incident.
