CLIFTON -- An internal affairs investigation into a city officer who was caught on camera 'brake checking' a motorist found that he was wrong in the way he performed the stop.

Last April, Omar B. uploaded a video of the March 19, 2016, incident that showed Officer Juan Velez suddenly slam his brakes while driving in front of Omar's car, almost causing a crash.

Omar, who asked that his last name not be used for safety reasons, provided NJ Advance Media with copies of documents he requested in the case. Velez was charged with two Administrative Rule Violations, according to the documents.

Detective David Perada of the department's Special Investigation Divison said Officer Velez was justified when he stopped Omar but the manner in which he did was a violation of departmental policy.

The Clifton resident posted the dashcam footage to Youtube last April, since then the video has been viewed more than 800,000 times.

Video of the incident shows the 2006 Infiniti M35x traveling between 22 and 29 miles per hour north up Van Houten Avenue before the driver was stopped.

The officer admits in the recording that he braked only because he felt the motorist behind him was following too closely. As a result, the driver was forced to brake quickly in the middle of the road.

"This cop could have hurt me, himself and anyone else who was behind me that couldn't stop in time," the poster said in the video.

Following the incident, Officer Juan Velez issued Omar three summonses: One for lack of a front license plate, one for tailgating and the third for tinted windows, a common summons in New Jersey.

Omar appeared in Paterson Municipal Court Friday for a hearing on the charges. The case was adjourned because John Klotz, Omar's lawyer, asked that the IA files be available in court as evidence in the case.

Velez, a 12-year veteran of the Clifton Police Department with an annual salary of $119,558, stormed out of the courtroom Friday.

Days after the original incident was reported, Omar alleged that Officer Velez approached him outside a Clifton restaurant and called him a "coward."

An internal affairs investigation found there was sufficient evidence to charge Velez with a violation regarding poor demeanor in that incident.

Both violations were classified as "sustained, internal disciplinary action." It is unknown what repercussions Velez faced as a result.

Clifton Police Department spokesperson Detective Sgt. Robert Bracken said Friday that the department would not release any information because, "IA investigations are entirely confidential."

Omar said he requested the documents shortly after the incident, and even though they are marked with a Nov. 22, 2016 date, he received them this week via certified mail.

Klotz said the summonses against his client should have been immediately dropped after the officer was issued the violations.

Omar, a 22-year-old NJIT mechanical engineering student, said Velez just got a slap on the wrist.

"He didn't have the right to stop me like that," said Omar Friday. "You don't need police training to to tell you not to get into accidents with motorists."
