At least seven NYPD officers have been arrested in connection to racketeering.

The Associated Press reports that the seven officers were the subject of a yearslong gambling and prostitution investigation.

Police say the probe was initiated by the Internal Affairs Bureau in 2015 following a tip from a fellow officer.

Dozens of civilians were also arrested in the case, which is being prosecuted by the Queens District Attorney's Office.

NYPD Commissioner James O'Neill released a statement saying in part, "Today, those who swore an oath and then betrayed it have felt the consequences of that infidelity. The people of this department are rightly held to the highest standard, and should they fail to meet it, the penalty will be swift and severe."

It wasn't clear when the officers will be arraigned.
