UPDATE (at bottom): Cop who assaulted teen now in jail on rape charge; shot ex-wife's new husband 24 times in 'self defense'

For the offense of not having his shirt tucked in, 15-year-old special needs student Marshawn Pitts was slammed into a wall of lockers and pounded repeatedly in the face by a police officer who broke the boy's nose and bloodied his mouth.

The Dolton, Illinois teen told a local CBS affiliate that the officer was cursing at him as he complied with the order to tuck in his shirt. Then, "it was just like, boom!" he said.

The assault, which took place in May, was recorded on a security camera at the Chicago suburb's Academy for Learning.

"The academy is a high school for special-needs students who are emotionally disturbed or struggle with behavioral disorders," noted Chicago Breaking News. "Marshawn was a student there because he suffered brain injuries when he was hit by a car years ago, [family attorney Edward] Manzke said."

During the recording, the officer stoops down and places a cup of coffee on the floor, then threw the teen into the lockers before pummeling him and pinning him to the floor in a maneuver known as the "face-down take-down."

"Zena Naiditch of Equip for Equality, a legal advocacy group that fights for the rights of people with disabilities, looked at the video and said the type of physical restraint used by the officer has killed students," CBS News reported.

Naiditch added that the hold can be lethal because those trapped by it are left unable to breathe. CBS noted that seven states currently prohibit officers from using the "face-down take-down."

The officer has not been identified, but due to the filmed evidence of the assault he has been terminated from the force.

Manzke told WBBM News Radio 780 that Marshawn has since transferred to a new school and the family is planning to file a lawsuit.

This video is from CBS 2 in Chicago, broadcast Oct. 7, 2009.

UPDATE: Cop who assaulted teen now in jail on rape charge; shot ex-wife's new husband 24 times in 'self defense'

The officer who brutally beat special needs student Marshawn Pitts has been identified as 38-year-old Christopher Lloyd, according to Chicago Breaking News, which spoke to Lloyd's father.

The news agency reported that Lloyd is currently in jail after being charged with the rape of a woman he knew and is facing a 20-year sentence should he be convicted.

The Chicago Tribune-backed service adds: "A lawsuit filed by his ex-wife, Nicole McKinney, last summer alleges he gunned down her new husband Cornel McKinney in front of their children outside their home on the 6100 block of South Langley Avenue on Feb. 17, 2008."

An autopsy revealed Lloyd shot the man 24 times, the agency found. He was not jailed at the time as Chicago police accepted his explanation that the killing was in self-defense.

Lloyd also reportedly told his father that the boy he was filmed assaulting had a history of behavioral problems and had cursed at him when told to tuck in his shirt.
