Johnny Depp Bodyguards Reportedly Attack Disabled Woman At Iggy Pop Show

Law enforcement sources tell TMZ ... 52-year-old Robyn Ecker filed the report claiming she was celebrating her husband's birthday at the Iggy Pop concert in L.A. -- treating him to $600-a-pop seats at the Palladium ... and Johnny was seated right beside her, surrounded by bodyguards.

Ecker claims she was having a blast, dancing her face off ... when she accidentally strayed a little too close to Johnny's table.

According to Ecker, Depp's bodyguards pounced on her out of nowhere -- grabbing her wrists and wrestling her to the ground. Soon as she regained composure, Ecker says she left and got herself checked out at the hospital.

Ecker's assistant tells TMZ, Robyn and her party had been drinking during the evening. Law enforcement sources tell us, Robyn appeared wasted when she made the report.
