Detroit police have released incredible footage of a gun battle that took place inside a precinct Sunday (January 23), between Lamar Moore and police.

The gun battle started when the 38-year old Moore, armed with a 20-gauge shotgun walked into the Northwestern District station and started dumping shots at cops for no apparent reason.

Police officers return fire, fatally wounding Moore, but not before he managed to shoot four of them.

In the video below which is shown from two different angles, you will see Moore calmly walk in before the shooting starts. At one point during the gun battle he jumps over the police desk as he and Cmdr. Brian Davis shoot at each other at point blank range.

After Davis is shot in the hand and back, he throws a trash can at Moore who is already mortally wounded.  He can be seen slumping to the floor as the trash can bounces over a desk.

The four wounded officers survived and are recovering.

So far police haven't discovered a motive for why Moore went on the shooting rampage.
