Pro- and anti-police demonstrators clashed Wednesday on New York’s Brooklyn Bridge, leaving four officers hurt and at least 34 people arrested.
One of the officers was hit in the head with a cane, and another officer was seen holding a bandage to his head with blood streaming down his face.
Terence Monahan, chief of department of the New York Police Department, was among those hurt, police say.
Wednesday's demonstration, called the Power of Prayer march, was organized by members of the clergy who say they support the police. Demonstrators carried signs that said, “Jesus Save New York” and “We Support the Police.”
The march came just hours before New York Mayor Bill de Blasio signed a series of police reform measures in response to the death in May of George Floyd in Minneapolis and other young Black men in the U.S., including Eric Garner on New York’s Staten Island in 2014.
The measures include a ban on chokeholds and a requirement that officers have their shield numbers visible at all times.
Earlier on Wednesday, de Blasio helped plan a Black Lives Matter mural in the Bronx.
