The Federal Bureau of Investigation on Monday issued a warning to police departments nationwide of a potential plot by an anarchist group to ambush cops on Halloween, according to multiple news reports.

A group known as the National Liberation Militia has proposed a “Halloween Revolt” encouraging member to dress in costume, cause a disturbance and then ambush police who come to help, the FBI warned.

The group has recommended members wear typical holiday masks and bring weapons like bricks and firearms, the New York Post reported.

NYPD officials told the New York Post there is no specific threat to New York City and said they were continuing to monitor the situation.
