The NYPD is investigating a hate-filled missive sent to an NYPD precinct station house in Brooklyn in which the writer threatens to murder white police officers and their families on Christmas Day and kill President Trump, officials said.

“Kill Donald Trump,” the two-page screed states. “Y’all families are not safe either. More funerals and silly bagpipes to listen to. Y’all scumbags have no balls.”

The hand-written letter that was sent to the 63 Precinct in the Flatlands with a return address in Carol Stream, Illinois, also includes racial threats.

“Black Power. Kill all white cops. Death to all racist punk cops. The new B.L.A. Fuck B.L.M, the letter reads, in an apparent reference to the Black Lives Matter movement against police brutality and the left-wing terror group the Black Liberation Army.

“Get killed on X-Mas day along with your filthy families,” the letter reads.

The NYPD confirmed it is looking into the letter’s origins.

The letter also includes comments about a police officer who was killed 32 years ago.

“F*** Eddie Burns,” the letter says, referring to Officer Edward Byrne, who was shot and killed in Queens in 1988 while protecting a witness in a case against a crack kingpin. “he is dead good!!!!!”

“We will do more than hit y’all over the heads with skate boards,” the letter states. “We will shoot your scumbag heads off.”
