A third case of people throwing buckets of water at NYPD Officers has occurred—this time in the south Bronx.

The video shows cops from the 42nd precinct running away as a crowd dares them to come closer.

That video emerged as police made their first arrest in the dousing of officers in Brownsville, Brooklyn over the weekend.

Courtney Thompson, 29, turned himself in and was booked with criminal nuisance, disorderly conduct and other charges. The incident occurred as police responded to complaints about a group along East New York Avenue tossing water on people.

"Our police came out here and they were called to this location,” said Assistant Chief Jeffrey Maddrey. “They were called about a disorderly group. And our officers showed a proper amount of respect."

Chief Maddrey said the pair of cops basically told the group to take it easy and didn't explicitly demand that they stop having fun in the water. That's when they were soaked.

Videos of the incident and of a dousing in Harlem were shared widely on social media, causing condemnation by the police union and an outcry by some politicians. In the Harlem incident, officers were soaked and one was hit in the head with a bucket as they tried to make an arrest.

In a letter to the New York Times, 27 African-American leaders from business, law and politics, wrote, “We were appalled at the recent verbal attacks on and water dousing of police officers in Harlem and Brooklyn.” They added, “This behavior is not at all representative of the millions of law-abiding citizens in our diverse communities.”

Public Advocate Jumaane Williams says police unions and elected officials should not be using the incidents to call for more aggressive police tactics.  

"We do want to make sure that these things don't happen again, but we have to continue to move in a direction of better policing," Williams said.

Members of Blacks and Latino Law enforcement organizations stood with Williams saying the community and cops must keep cool heads.

"It is totally unacceptable for officers to come to work to do their job and be treated that way. Something like this can escalate very, very seriously," said Gerald Nelson, from the National Organization of Black Law Enforcement Executives.

Williams says some people may be upset over the Eric Garner case or similar situations, but he says attacking an officer in any way is wrong.
