Lt. Fred Pickering of the New Canaan Police Department was cleared of criminal activity by the state for his role in a February bar fight.

The New Canaan Police Department announced at 4:03 p.m. Tuesday that State's Attorney David Cohen has found insufficient evidence for criminal activity in the case.

"After a thorough review of all the evidence presented, I have concluded that there is insufficient evidence to prove beyond a reasonable doubt that any specific person has committed a crime," Cohen said in the press release.

Pickering was placed on administrative leave on March 11 following a complaint that he was involved in a fight at Tequila Mockingbird Restaurant on Feb. 23 while off duty.

According to the report, a group of individuals went to the police department at about 11:45 p.m. Feb. 23, claiming one of them was involved in a physical altercation with Pickering.

The complainants also stated that an individual with Pickering used racially offensive language.

The release also stated the department started an internal investigation of Pickering over whether his conduct, though not criminal, violated any of the rules and regulations of the department's Manual of Conduct and Discipline.

New Canaan Police Capt. Krolikowski would not put a timeline on the internal investigation.

"Hard to say. It really depends," he said about how long such an investigation might take. "I don't even want to guess."

He did confirm that as of right now, Pickering would remain on paid leave for the duration of the investigation.

"I appreciate attorney Cohen's decision in the matter," Pickering's attorney Eugene Riccio said. "My client would like to express his thanks to the many people who supported him."
