Police have issued an appeal after a man was subjected to a stream of homophobic abuse in the street by a Muslim patrol for contravening strict Sharia law.

Scotland Yard is investigating a video clip uploaded to YouTube in which a man calls a fellow pedestrian "a fag" and is asked to leave the area.

During the clip which was filmed by the attacker at night, the passer-by, who is carrying a shoulder bag, is seemingly targeted because of the shoes he is wearing.

"Don't you know this is a Muslim area?" the victim is asked by the Muslim patrol.

He is then asked three times "what's wrong with your face. Why are you dressed like that?"

The Muslim patrol then tells the man he has to leave.

"Get out of here, you're walking through a Muslim area dressed like a fag mate. You need to get out of here.

"Look at your shoes, you're dirty. You bloody fag. Don't stay here no more. Look at you, you mug."

During the exchange, an accomplice's voice can be heard repeating "homosexual."

The victim did not stop walking along the street, the name of which has yet to be identified by the police.

Calling for the man to come forward, detective chief inspector Wendy Morgan from Tower Hamlets borough said: "The Met takes such homophobic behaviour very seriously.

"This man is a crucial witness in the investigation and would encourage him and anyone else with information relating to this incident to make contact in confidence as soon as possible."

Muslim patrols on London streets have made headlines around the world, after a slew of shocking videos emerged of young men harassing pedestrians in the east of the city by claiming Sharia law was in force.

Radical preacher Anjem Choudary has defended members of a patrol in Whitechapel, who triggered online outrage after being arrested for assault and grievous bodily harm.

Choudary told IBTimes UK: "There is a clash between Islam and liberal democracy in hotspots areas of London.

"There is a prevalence of prostitution and drunkenness in London and the police are not dealing with it. The problem is so widespread that I'm not surprised more Muslims are not taking it into their hands."

Choudary called for the patrol be commended.

A total of four people have been arrested in connection with the incident on suspicion of suspicion of grievous bodily harm and public order offences.

On Thursday (January 24) a 25-year-old man and a 29-year-old man was held were held at an east London police station.

Ealier, two other men, A 22-year-old and a 19-year-old were held, were arrested over the YouTube clips.
