Unarmed black man fatally shot by reckless police in Oklahoma

A US black man that was fatally shot by police in Tulsa, Oklahoma last Friday was unarmed, police officials say.

A video, taken from a police dashcam, was released on Monday which shows that 40-year-old Terence Crutcher had his hands up when he was tasered and then shot by police.

The incident began after an officer responded to a report of a stalled SUV in the middle of the road in Tulsa, where there was another police car stopped behind the disabled SUV.

In the video, it can be seen that Crutcher walked away from the police cars and toward his own car with his hands over his head.

Then, one female officer followed him with her gun pointed at the victim’s back and then three other officers joined her, which obscured the camera’s view of the black man.

He then collapsed with one officer saying on the police radio, “I think he may have just been Tasered” and then another one, saying, “shots fired.”

He was later pronounced dead at a hospital.

Police said that he was shot while he had no weapon on him or in his vehicle.

“The video is very disturbing, it’s very difficult to watch,” Tulsa Police Chief Chuck Jordan said in a press conference Monday before the video’s release. “We will do the right thing—we will not cover anything up.”

"We will achieve justice in this case," Jordan added.

On Monday, people took to the streets outside the Tulsa County courthouse and waved signs that read, "This Stops Now" and "Not Going, Keep Protesting."

"Hands up, don't shoot," protesters chanted.

The US police are accused of using excessive force against African-Americans. The deaths of unarmed black men and women over the past years have sparked protests nationwide under the banner called - Black Lives Matter.
