A startling leaked video (below) shows three police officers using a stun gun on a man 20 times within half an hour while he's bound. The man later died.

On May 4, 2013, Linwood Lambert was detained just before 5 a.m. when police answered a noise complaint and discovered Lambert acting suspiciously and seeming to be delusional in his Super 8 motel room in South Boston, Virginia, reports MSNBC.

The officers had no grounds to arrest Lambert, 46, but reportedly decided to restrain him and take him to a hospital.

MSNBC acquired the video of the officers using the stun gun and arresting Lambert, along with documents with eyewitness accounts of the incident.

During the car ride, Lambert reportedly became restless and kicked out the back window of the squad car as they pulled up to the hospital entrance.

The officers then bound Lambert’s ankles and started to use the stun gun on him, reports MSNBC. He instantly falls to the ground, powerless to break his fall because he is handcuffed, the video shows.

Cpl. Tiffany Bratton, one of the three officers, used her stun gun 15 times, with 10 of those hits striking within a two-minute span, reports MSNBC

Lambert was hit with the stun gun for a total of 87 seconds, a level that could cause death, according to the Daily Mail.

After Lambert falls to the ground in front of the hospital door, Bratton says, “Every time you get up, I’m going to pop you.”

Lambert can be heard screaming “I didn't do nothing!” Bratton responds with, "I’m going to light you up again — roll over, roll over, turn over!"

The video shows Lambert is hit with the stun gun again and his legs are shackled. Lambert then confesses that he was under the influence of cocaine while the officers tell him he is under arrest for disorderly conduct and destruction of property.

Lambert was then arrested by the three officers, Bratton, along with Officer Clifton Mann and Officer Travis Clay, and driven to the police station instead of the hospital.

The video shows the three officers throw Lambert back in the police vehicle. When they see him squirm, one of the officers is heard saying, “Sit up or I’m going to tase you again."

Lambert is then tased again by two different tasers. Clay also tased the man right on the neck. He alleged Lambert was trying to bite him, but the video does not support Clay’s claim.

When Clay saw Lambert was unconscious upon arrival at the station, he reportedly called an ambulance.

Lambert was dead when he reached the hospital at 6:06 a.m., a little over an hour after police first arrived at the motel.

Several nurses who were working shifts at the hospital that morning said they witnessed the three officers simultaneously tasing Lambert, reports MSNBC.

Lambert's death was ruled to be the consequence of cocaine intoxication, but after seeing the video, his family is suing the South Boston Police Department for $25 million, reports MSNBC.

“I can’t say what I was thinking, it was awful,” said Linwood Lambert Sr., Lambert’s father, after watching the video of what the police officers did to his son.

“You wouldn’t do any human or any species like that. I don’t think anyone could hate someone that bad to inflict pain such as what they did.” Adding, “I don’t see anything that he did in that tape that would provoke them to do what they did.”

The three officers involved have never been indicted and all have since been promoted.

When asked for a comment, the South Boston Police Department did not respond to MSNBC. The department's current instruction manual says using a stun gun “is no longer justified once the subject has been restrained.”
