NEW YORK - NYPD Chief of Department Terence Monahan is among three officers injured Wednesday during dueling protests that moved across the Brooklyn Bridge and into Manhattan, the NYPD said Wednesday.

One group was supporting the department and rallying against gun violence. The other was voicing their support to de-fund the NYPD.

Monahan suffered a cut on his hand, according to the NYPD.

Sources say all the injured officers were being treated at area hospitals for minor injuries.

The NYPD says 37 people - 23 male and 14 female - were arrested at the protest.

The department's official Twitter account tweeted out video (WARNING: disturbing content) that it says shows officers being "violently attacked by protesters crossing the Brooklyn Bridge." Police say the person seen hitting the officers in the video has not been arrested at this time.

The Power of Prayer march involved members of the clergy, community activists and police.

It came together in response to the recent spike in gun violence across the city, including a shooting early Wednesday morning that left one person dead and five others injured.

Community leaders are calling on the Mayor Bill de Blasio and the City Council to work together to end the violence. 

They accuse the mayor of allowing anti-police protesters and Black Lives Matter to dictate city policy. 

The group was calling for the mayor to not sign police reform legislation they say will keep police from doing their jobs and getting guns off the street. 

Earlier in the day, Mayor de Blasio unveiled a two-pronged approach to reduce street violence focusing on Central Brooklyn.

He says there will be increased police presence in Crown Heights and Bedford-Stuyvesant. Public events like peace marches will be led by local community and clergy leaders.

There will also be street fairs offering resources to help people find jobs, housing and youth services.

Mobile trauma units will also be on-duty to provide counseling for people in neighborhoods affected by gun violence.

The mayor and other lawmakers say they believe these actions will have an immediate and positive effect.

"We saw it in Harlem on Saturday night, the Cure Violence movement out in full force occupying the corners. This is the way forward," De Blasio said.

"Where there is an uptick in crime, we're gonna have an uptick in services and really those areas with the necessary services. Because what we understand is while depraved individuals were pulling the trigger, society is responsible for the bullets that were loaded into that gun," said City Councilman Robert Cornegy.

Community leaders in Bedford-Stuyvesant also plan on meeting with the NYPD next week to discuss future anti-gun violence measures.
