A Delaware trooper was caught on video pulling a gun on an unarmed black man during a traffic stop last Thursday.

In the clip, Mack Buckley is seen sitting in his car waiting on the officer to come over to his vehicle.

'Out of the car,' the officer orders Buckley, who tells the officer that he's not getting out.

'No, no, no. You cannot, you cannot pull me out of this...' Buckley tells the officer just seconds before the trooper pulled out his weapon.

The officer is heard telling Buckley that 'I'm not f**king with you,' as he pointed the gun at him.

'Why are you pulling the gun on me?' Buckley yelled at the officer before throwing his phone into his seat and putting his hands in the air.

During the incident, Buckley repeatedly asks the officer why he pulled the gun on him as the trooper continued to tell him to unbuckle his seat belt and get out the car.

'Stop reaching for sh*t,' the officer told Buckley, who attempted to grab his phone.

The chaotic scene continued to unfold with the officer and Buckley yelling at one another as Buckley questioned the need for the gun.

Buckley was subsequently arrested and charged with resisting arrest and several traffic violations, according to Delaware Online.

It's unclear why Buckley was stopped and authorities said they are investigating the incident.

Delaware State Police said 'the video is currently under review'.

Buckley shared the video on his Facebook page. It has been viewed more than 4,000 times and has more than 100 shares.

He also shared his account of the incident on his Instagram page.

'First off... I'm not a wanted person. I'm not on probation. 2nd... at the time of the stop I was not a suspect in any crime or offense,' Buckley wrote.

He said he was 'allegedly pulled over for speeding, but pulled over 2 miles from where I was allegedly speeding at'.

Buckley said he was driving his mother's vehicle at the time of his arrest.

'I am a human being... with rights... not a suspect. And it's disturbing that people would look at me and label me a suspect because I got pulled over by the police or the tone of my skin,' the father-of-three added.

Buckley is the founder and co-owner of Grynde Hawse, LLC and Print 25 Apparel.

He's also a self-published author.

No further information was available from police and authorities did not release the identity of the officer.

But Buckley said the officer in the video was Corp O'Neil of Troop 7 in Lewes, Delaware.

The incident occurred in the Slaughter Neck neighborhood of Sussex County, Delaware.
