NAPLES, Italy — The identity of a man arrested in connection with a shooting Thursday at Naval Support Activity Naples in Italy is being withheld pending potential charges.

No one was injured in the incident, which involved an airsoft rifle, officials said.

It was unclear Friday whether the man, who is a “person of interest” in the case, was still in custody. His name will be released only if charges are filed, Lt. Jamie Moroney, an NSA Naples spokeswoman, said Friday.

It also was uncertain Friday what charges he may face, but personal weapons, including airsoft guns, are prohibited on base, Moroney said.

Moroney declined further comment on the investigation, which is being led by the Naval Criminal Investigative Service.

Often realistically modeled to look like traditional firearms, airsoft guns shoot nonmetallic soft pellets. They are frequently used for target practice and military-style games.

The man’s arrest followed reports Thursday evening of what sounded like gunfire near Naples Middle High School, at the base’s Gricignano di Aversa site, triggering a two-hour lockdown of the base and a search for a potential gunman.

The Gricignano di Aversa site includes schools, housing, a commercial center, a hospital and a hotel. It is about 13 miles from the base’s Capodichino site, which includes administrative and support services and is home to the U.S. 6th Fleet.

Approximately 8,500 people are assigned to the base, according to its website.

About 8 p.m., security forces arrested a man at an on-base apartment and confiscated an airsoft rifle, officials said.

“Tonight was a good reminder of why we train, so that we can have a unified response when we need to protect our community,” the base said Thursday on Facebook.
