EDISON - News 12 New Jersey has learned new details on how personal information about New Jersey Transit police officers was leaked online.

The personal information leaked involved 55 officers and was posted as a series of tweets by a hacker group known as the Caliphate Cyber Army, formerly known as the Islamic Cyber Army. That group was reportedly working for the Islamic State.

The information, which included home addresses, cellphone numbers and home phone numbers, was obtained when the hackers apparently accessed the database of Action Uniforms, based out of Egg Harbor Township. NJ Transit police officers purchase their uniforms through this company.

The officers’ information was posted on Islamic State websites so that the officers would be attacked, according to the NJ Transit police union.

The union released a statement that said in part, "Our members have been individually targeted for ‘lone wolf’ attack at their homes by an international terrorist organization. While we patrol against terrorist attack every day we work, we are horrified that we are now bringing this threat home to our families.”

A NJ Transit spokespeson also responded to the incident, "NJ Transit's information system was not compromised, however some information was breached from an outside vendor.  The NJ Transit police department is working with the Department of Homeland Security and the FBI on this matter."

All the officers affected have been alerted and police have increased patrols in several neighborhoods. The union says that they have no choice but to continue to use Action Uniforms, but will be exploring legal options.

News 12 New Jersey called Action Uniforms and the person who answered the phone first said that they were unaware of the situation. When pressed further the person on the phone said that it was a serious security issue and did not want to speak about it, before hanging up.
