A black man was punched in the face by a white police officer while he was waiting for his mother to pick him up from a Texas hospital.

The shocking blow was recorded on tape at Harris Methodist Hospital in Fort Worth and shows Henry Newson, who had spent two days in the hospital, borrow a stranger's phone to call his mother while talking to a suspicious cop.

When an argument escalates, off-duty officer Jon Romer enters the scene, pushes Newson out, and suddenly punches him in the face before pinning him to the ground.

The scene unfolded on November 5, 2016 and was recorded on hospital surveillance footage and body cameras, obtained by WFAA.

Newson, now 21, is suing Officer Romer, the hospital, and security guards for unspecified damages.

Newson was in Harris Methodist Hospital in Fort Worth, Texas for two days recovering from an illness. After he was released he borrowed a stranger's phone in the hospital lobby (above)

The harrowing footage sees Newson enter a lobby and borrow a stranger's phone after he had been in the hospital for two days recovering from an illness.

A cop immediately hovers around him saying: 'I’m just trying to figure out what you’re doing'.

Newson asks to be left alone and becomes frustrated with the officer's questions.

'She’s picking me up from here. I have nowhere else to go,' he says.

'You won’t leave me alone. For real though. You keep asking me ignorant questions like do you know what hospital it is? Yes, my mother knows what hospital it is.'.

Officer Romer, who was off-duty and working private security that day, bee-lines for Newson to usher him out of the building, placing his hand on his chest and pushing him out.

Newson tries to calm him by calling him 'bro' which triggers Romer to punch him and put him in a choke-hold.

Two other officers help handcuff Newson on the ground.

He was arrested for trespassing and resisting arrest, but those charges were later dropped. He spent two days in jail.

Newson filed a lawsuit in November accusing Romer of a 'clearly racially motivated attack' and seeking $1million in damages, according to Star-Telegram.

'This was a young African-American kid with no criminal history, no criminal record. He'd been in the hospital for two days and he was waiting for his mom to come pick him up,' his attorney Matthew Bobo said to WFAA.

'The officers knew why he was there, he complied with everything they asked him to do and they still beat him up,' he added.

Video footage at the hospital captured the moment Newson was on the phone with his mother asking a police officer to leave him alone

Newson pleaded with officers to call his mom. They refused because he was over the age of 18

Speaking to NBC5, Bobo added Newson 'doesn't resist, he doesn't fight back'.

'It was fast. It was violent and there was nothing that would have indicated that that should have happened or was going to happen,' he said.

Officer Romer, 38, was indicted March 15 in the case on charges of official oppression, making a false report to a peace officer, and aggravated perjury, according to Dallas News.

Romer told investigators in 2017 that his use of force was approved – despite being off duty – and Romer lied under oath saying he told Newson was under arrest before he hit him, according to indictment documents.

He was released from Tarrant County Jail that same day after posting bond.

Romer was an officer for 15 years has been placed on restricted duty.

This isn’t Romer’s first spat with the African American community.

In 2011 Romer was involved in the shooting of Charal 'Ra Ra' Thomas, 32, who was a handicapped father.

Thomas did not follow police orders to exit his vehicle and drove with Romer’s arm trapped in a window, dragging Romer along.

Romer fatally shot Thomas as he drove, right in front of an adult passenger and Thomas’ three children in the vehicle.

'Why was a police officer who has used deathly force been allowed to remain on the streets until the day of his indictment?' Michael Bell spokesman for the Tarrant County Local Organizing Committee said in a press conference last week

'Who made the decision to not hold Romer accountable for his actions once they were uncovered?' he added.
