A New York City man has been charged with posting a threat against police hours after two officers were killed by another man who had signaled his planned attack online.

The New York Post reports that 18-year-old Devon Coley was arraigned Monday on a charge of making a terroristic threat.

The Post says Coley — who also is facing unrelated gun possession and other charges — posted a photo of a gunman shooting at a patrol car with the phrase “73Nextt.” It was an apparent reference to the 73rd police precinct in his Brooklyn neighborhood.

His lawyer told a judge Coley wasn’t planning to follow through on the message. Prosecutors called the charges serious and sought $250,000 bail.

A judge called the posts inflammatory but released Coley without bail.
