An officer involved was dismissed following the death of a black man in a controversial police operation in the US state of Ohio.

The police officer Adam C. was fired for using disproportionate force, not turning on his body camera and not helping the dying person, said Columbus Mayor Andrew Ginther on Monday (local time) on Twitter.

The police in Columbus were called to a garage by a local resident last week.

When the 47-year-old Andre Hill approached her shortly after the officers arrived, Adam C. is said to have shot him.

The seriously injured Hill later died in hospital.

Police said he had a cell phone in his left hand when he met the officers.

The right hand was not visible.

The police did not find a weapon at the scene.

Police chief Thomas Quinlan said Monday the evidence provided a clear basis for the police officer's resignation.

This must now face the investigators' questions.

The head of the agency had already found clear words shortly after the controversial operation: the official's violation of the agency's rules cost an innocent man's life.

C. is white.


Police violence against blacks has repeatedly triggered violent protests in the United States this year.

The most prominent victim was the African American George Floyd, who was killed in a brutal police operation in Minneapolis, Minnesota, in late May.

Under the motto “Black Lives Matter”, there were mass demonstrations against police violence and racism for months in the USA, some of which were overshadowed by riots.
