Prosecutors say a New York City detective alleegdly invented a tip about an illegal gun then forged paperwork to collect a $1,000 reward.
Prosecutors say that in November 2012, detective John Malloy created a fake anonymous tip for an already-recovered 9mm semi-automatic pistol.
They say he forged the signature of his supervisors and another detective to claim the reward money.
Internal affairs officers investigated the case. Malloy's been charged with official misconduct as well as multiple counts of forgery and filing a false instrument.
Court papers show Malloy told investigators he was having health problems and was under a lot of stress when he signed his colleagues' names.
Malloy was arraigned Thursday in Manhattan. He pleaded not guilty and was released. His attorney didn't immediately return a call.
