Iraq Veteran Beating Tape: Video Of NYPD Assaulting Walter Harvin Released (VIDEO)

The Manhattan DA's office has released the highly controversial footage at the heart of a police brutality case involving an Iraq war veteran.

Officer David London is on trial for assault and falsifying a police report after being caught on tape beating Walter Harvin with his baton even after the vet had been handcuffed.

On Monday, London's partner Mohammed Khan testified that Harvin was needlessly aggressive before, during, and after the incident.

Reports the Daily News:

Harvin yelled "I'll kill you mother----er," and "I'll f--- you up" as London hit him repeatedly, Khan said. He also kicked the cop while on the ground, Khan said.

The 28-year-old Harvin, who recently returned from Iraq, was stopped by officers after trying to enter his mother's West 93rd Street housing project without a key.

The video shows Harvin shoving London in front of a group of people. The officer and Harvin then exchange words, inaudible on the tape.

After a few moments London proceeds to strike Harvin with his baton and continues doing so while Khan tries to cuff him. London hits Harvin at least 20 times.

Harvin has since disappeared and is not expected to testify at the trial.

Khan faces departmental charges for his role in the attack.
