Eleven Port Authority police supervisors are facing disciplinary action for allegedly failing to make sure officers did their jobs at PATH stations in New Jersey and New York.

Six lieutenants and five sergeants didn't ensure patrol officers performed their duties, the Office of the Inspector found after an investigation.

Most of the violations took place during the midnight to 8 a.m. shift, the Port Authority of New York and New Jersey said in a press release Tuesday morning.

In December, the Port Authority announced that disciplinary action had begun against 44 officers who allegedly spent part or most of their shifts in break rooms instead of patrolling the station.

The Port Authority's Chief Security Office became aware of the misconduct in May 2016, leading to an investigation by the Office of the Inspector General.

The investigation into the supervisors uncovered "serious" misconduct and is supported by video evidence.

Misconduct among patrol officers was first found at Hoboken station before investigators turned their attention to Newark Penn Station, and the Christopher Street, 33rd Street and World Trade Center stations.

A spokesman for the Port Authority police declined to provide the names of the supervisors, noting it was not a criminal matter.

The Port Authority Police Sergeants Benevolent Association didn't immediately return a call seeking comment. A person who answered the phone at the Port Authority Police Lieutenants Benevolent Association said the membership was in a meeting but might provide a comment later.
