Amber Heard: Cops Interviewed by LAPD Brass ... We Saw No Injuries

The 2 officers who interviewed Amber Heard the night she was allegedly attacked by Johnny Depp have spoken with LAPD brass, and our sources say they are adamant ... Amber had no visible injuries.

The officers spoke with superiors Tuesday afternoon and said they had no idea Johnny Depp was involved at all -- the 911 call came in under the name Heard, and they did not associate her with Depp.

The 2 cops say the information they had when they knocked at her door was only that there was a domestic dispute. Amber opened the door just a crack but would not let them in. They questioned her through the door and she said it was a simple verbal argument with her husband. She never mentioned Depp by name.

The officers told her they needed to make sure she wasn't declining help under duress, so they insisted on coming in and speaking with her. Amber obliged, and the officers say they looked at her closely enough to determine there were no marks, swelling or bruising on her face or other exposed parts of her body.

Our LAPD sources say precisely what several doctors told us ... if Johnny threw an iPhone at her pitcher style, and then followed up with hair-pulling and hitting, there would have been swelling at the very least, and most probably some immediate bruising or redness. The officers saw nothing.

The cops insist if they had seen any sign of injury they would have taken a report and tracked down the husband.
