JERSEY CITY - An undersheriff's son could face disciplinary action after sources say friendly horseplay went too far and he stabbed a fellow officer inside the Hudson County Administration Building.

Officials have been mostly mum on the mid-August incident, but multiple police sources told The Jersey Journal the incident involved Andrew Conti Jr., a sheriff's investigator who is a son of Undersheriff Andrew Conti. The elder Conti retired as captain in 2008 and was rehired as an undersheriff in 2011.

Conti Jr. and at least one other officer were horsing around near the entrance of the building, sources said and at some point, he took out a knife and stabbed the other officer in the hand. While the officer's injuries weren't said to be serious, he was treated at a hospital, sources said.

After the incident, Undersheriff Andrew Conti Sr. pulled his son aside and slapped him while both were on duty, the sources said.

When asked about the stabbing involving Conti Jr., sheriff spokesman J.P. Escobar only said "it is being investigated by the (county) law department" and he declined to provide any details about the incident, including the date, time, and exact location of the alleged stabbing.

Sources say the stabbing was classified as an "accident" and criminal charges were not brought.

An Open Public Records Act request for documentation of the incident was denied by the county. In its response to the OPRA request, the county said there was no crime committed and police were not dispatched to investigate the incident.

A Hudson County spokesman could only confirm a disciplinary hearing has been held. Sources say Conti Jr. is currently still working. Requests for a comment from Conti Jr. and Hudson County Sheriff Frank Schillari were not returned through the department's spokesman.
