US: A black man died after being struck repeatedly by Cincinnati police wielding metal nightsticks, and the city's mayor said yesterday a videotape showed that the officers were defending themselves.
The cause of death was under investigation.
Black activists say Sunday's death of Nathaniel Jones (41) was another example of brutality involving Cincinnati police.
The fatal shooting of an unarmed black man by a white police officer in April 2001 prompted three nights of rioting in the city.
The officers who were at the scene - five whites and one black - were placed on administrative leave, which is policy while investigators examine any police encounter that results in a death.
The confrontation with the 28-stone Jones was video-taped by a camera on a police car. It shows police struggling to arrest Jones and one police officer repeatedly hitting him with a truncheon.
After seeing the video, Mayor Charlie Luken rejected activists' demand that he force police Chief Thomas Streicher to resign.
"What I saw was a 400-pound man violently attacking a police officer in a manner that put the lives of police officers at risk," Mr Luken said.
"While the investigations will continue, there is nothing on those tapes to suggest that the police did anything wrong." Mr Luken said he agreed with the initial police assessment that the officers defended themselves as they were trained to do when attacked. The officers called for an ambulance when Jones appeared to be in distress. He died within minutes of arriving at the hospital.
Black activist groups staged an economic boycott of Cincinnati after the 2001 shooting of Timothy Thomas (19) who was wanted on prior charges of fleeing police when he ran from officers. Officer Stephen Roach shot him and was later cleared at trial of criminal charges.
