This is the shocking moment an innocent shopper buying a Valentine's Day present for his girlfriend was wrestled into a headlock by a policeman.
Dean Davis said officers subjected him to a "humiliating and unprovoked attack" inside a shop in Augusta Street, in Birmingham's Jewellery Quarter.
He said he was gripped by his throat and his head pushed on to a glass counter after being confronted by two officers.
Mr Davis, who was buying earrings for girlfriend Tina Ebanks, said he was then taken to a police van and searched.
His van, parked nearby, was also examined before he was finally freed.
Mr Davis said officers told him they were investigating reports of suspicious behaviour in the area.
But he claimed the white friend he was with did not suffer the same ordeal.
Now the 39-year-old, from Rubery, has complained to West Midlands Police over his treatment.
The force confirmed its professional standards department was investigating his claims of assault.
Former BT engineer Mr Davis, who does not have a criminal record, said: "I have clearly been victimised.
"I had only been in the shop for around four minutes and was looking down at a glass cabinet when two officers buzzed the shop door and the owner let them in.
"They stood near to the door and said two people had been behaving suspiciously in the Jewellery Quarter.
"One of them asked for my name and identification.
"I told him I did not have any identification with me.
"He then approached me, took his book out and informed me that he could arrest me for not giving my details.
"I asked: 'What am I under suspicion of?'
"He then immediately put his book away and started poking at my chest.
"I continued to ask him what I had done.
"Within a matter of seconds I was gripped by my throat and was put in a headlock, my head was pushed on to the glass counter, more police officers entered the shop and piled on top of me.
"I had stood with my arms folded and had not tried to resist or behave violently."
A stop and search form given to Mr Davis after the February 14 incident gave no clear reason for the stop.
He added: "I was left gobsmacked by the whole thing. It was completely humiliating.
"I had bought jewellery from that shop at least four times in the past and even the owner was asking police what was going on.
"I went back in to meet my friend, but it was a terrible experience and has really shaken my confidence in the police.
"I have no idea why it happened. I was wearing a cap, I looked a bit scruffy that day and I'm black.
"My white friend was not searched in the same way or dragged out of the shop even though they said two people were acting suspiciously."
Det Chief Insp Debra Doyle, of West Midlands Police Professional Standards Department, said: "West Midlands Police has received a complaint from Mr Davis about this. The matter is currently being investigated by the Professional Standards Department."
Young black men are 28 times more likely to be stopped by cops
Senior councillors have urged the new West Midlands crime commissioner to tackle the "clear inequalities" highlighted in police stop and search figures.
Figures presented by the StopWatch human rights group and thinktank Brap claimed young black men in Birmingham were 28 times more likely to be stopped than young white men.
Young Asian men were 8.7 times more likely to be stopped.
Coun Waseem Zaffar, chairman of Birmingham City Council's social cohesion and community safety watchdog committee, said he would be writing to crime commissioner Bob Jones to demand action.
"This has been a problem for 30 or 40 years and something needs to be done," he said. "There is a clear inequality and there is a lot of concern in our communities about what is happening.
"I know that Bob Jones is arranging a stop and search summit and I will be writing to him to make sure that he takes up this issue as a priority."
The committee heard there were 33,757 stops in the West Midlands in 2011/12 under section one of the Police and Criminal Evidence Act, a 40 per cent hike on the previous year. But that rise was eclipsed by the 105 per cent increase in stops under Section 60 of the Criminal Justice and Public Order Act, which added another 657 stops to the tally.
The figures claimed young black men were 28 times more likely to be stopped under section 60 and Asians were 8.7 times more likely to be stopped.
But just six per cent of stops led to arrests, it was alleged.
The Rev Carver Anderson, interim chairman of the African and Caribbean Strategic Community Alliance, said how people were stopped was often as important as why.
He revealed he had been stopped and searched 25 years ago when he was carrying a squash racket in Birmingham and the same thing had happened to both his adult sons.
"There is a deep concern about this stark disproportionality," Rev Anderson said. "The community is willing to work in conjunction with the police on this issue but it has to be in an honest and transparent way.
"If these issues are not addressed I expect we will be here in five years talking about the same problem."
Chief Supt Steve Anderson, of West Midlands Police, told the committee a number of factors influenced the stop and search figures.
"The stops respond to particular crimes in areas where there are high crime levels, which are typically linked to higher levels of deprivation.
"These areas often have a higher black and minority ethnic population. They are also driven by crime profile description.
