An Ohio truck driver accused of killing his wife, her parents and aunt was swarmed by officers in a Walmart parking lot and pinned to the ground in a dramatic arrest captured on video.

Gurpreet Singh, 37, was walking through the parking lot of the Branford, Connecticut, store on July 2 when four cop cars cornered him at a median, dashcam footage obtained by the Daily Mail shows.

As officers clad in SWAT gear rushed toward Singh with their guns drawn and a police dog in tow, Singh put his hands in the air and dropped to the pavement on all fours.

Cops, some of them wearing bulletproof vests and toting rifles, thrust him to the ground and handcuffed him before leading him into a police car.

Singh is accused of fatally shooting his wife and her three family members in April in his apartment in the Cincinnati suburb of West Chester, Ohio.

Singh’s wife Shalinder Kaur, 39, her father Hakikat Singh Panag, 59, mother Paramjit Kaur, 62, and aunt, Amarjit Kaur, 58, were all found with gunshots to their heads after Singh called cops and said he came home and found them “bleeding.”

“They’re all down … no one’s talking,” he told a dispatcher, Fox 19 in Cincinnati reported.

Cops questioned him that night, but let him go.
