Secaucus police arrested a Bergen County sheriff's officer for allegedly driving drunk four days after the officer sued South Hackensack over injuries he claims he suffered during a night of drinking with township firefighters.

Brian J. Smith, 24, a two-year member of the Sheriff's Office, will appear in Secaucus Municipal Court on July 9 to answer charges stemming from his June 20 arrest. These include driving under the influence of liquor or drugs, refusing to take a breath-alcohol test, having an open container in the car and reckless driving.

Smith also faces a civilian complaint from the same night alleging that he, while drunk, restrained Jeter Serrano-Artiles of Paulanne Terrace by grabbing his arm. Smith also ordered Serrano-Artiles’ father to put his hands on the hood of a car, arrest documents said.

Serrano-Artiles had called police at 11:35 p.m. to report a suspicious male in a 2011 gray Toyota Camry, according to Capt. Dennis Miller of the Secaucus police. Miller said Smith’s drunken state led to the altercation, which was over by the time officers arrived. Serrano-Artiles filed the complaint in Municipal Court the next day, Miller said, and Smith must respond to the charge as if police arrested him for it.

The Sheriff's Office confirmed Smith's arrest and said he had been "administratively reassigned pending further investigation." But a spokesman refused to detail Smith’s duties before or after the incident, saying only that the officer was off-duty when it happened and that his assignment “does not require the operation of an agency motor vehicle.”

Smith did not respond to a request for comment, nor did Neil Weiner, his Hasbrouck Heights attorney. A phone for Serrano-Artiles listed in public records for his address rang with no answer..

Smith, who lives in South Hackensack and serves in its volunteer Fire Department, is suing the township and fellow volunteers Brandon Reczkowski and Anthony Moreno for allegedly hitting him with a department fire engine during a drinking escapade last summer.

Filed June 17 in state Superior Court in Hackensack, the suit claims the trio drank at a "wetdown party" in Fair Lawn held to celebrate that town's purchase of a new fire engine. They then visited multiple unnamed establishments, where Reczkowski and Moreno continued to drink, the suit said.

At some point the truck hit Smith, leaving unspecified injuries that caused him “severe and excruciating pain, as well as extreme mental anguish,” the suit says. Smith alleges that Reczkowski and Moreno were careless and negligent because they were drinking while driving the engine.

Ian Doris, the Rutherford attorney representing the two, declined to comment.

Smith is now seeking compensatory damages to cover his injuries, which the suit says required medical care and have since stopped him from “enjoying the normal fruits of his existence, both socially and economically.”

The suit also names the Fire Department and the fire chief as defendants.

David Nasta, the township’s attorney, previously said Smith fell off the moving truck and rolled under the wheel.

On Tuesday, Nasta said the allegations against Smith could affect his lawsuit.

“Very often, an individual’s actions can affect their credibility in a court proceeding,” Nasta said.

No hearing date has been set, he said.
