NEW YORK, USA - SOME 200 people were arrested in New York, police said, after city-wide protests against last month's acquittal of three policemen who killed an unarmed black man on his stag night.

'About 200 people were detained. All of them have been released now,' a police spokesman said, adding that there were no reports of violence or people wounded during the demonstrations, staged at various locations in the city on Wednesday.

Civil rights activist Al Sharpton was among those held, a police spokeswoman indicated earlier.

On November 25, 2006, three policemen in plain clothes fired more than 50 bullets at a 23-year-old black man, Sean Bell, as he left a club where he had been celebrating on the eve of his wedding.

Bell died on the spot and two of his friends were wounded. An investigation showed that none of the victims were armed.

Two of the detectives, Gescard Isnora and Michael Oliver, were charged with manslaughter and faced a possible 25 years in jail. The third, Marc Cooper, faced a year in jail on the lesser charge of reckless endangerment.

Last month, a court in the borough of Queens, where the shooting took place, acquitted all three men.

The police officers had been staking out the nightclub where Bell had gone for his stag night. They said they fired their guns after Bell's car nearly ran them over, and always maintained that he and his friends were armed.

Bell's cousin, Robert Porter, 44, said that the protesters would keep up their demonstrations 'every day, with the sun shining or under the rain'. 'We want justice, it is as simple as that. I don't care to be arrested, because we are fighting for a reason,' he said.
