The leading Democratic mayoral contenders demanded law enforcement step up their probe into the vandalism of George Floyd statues with slogans from a notorious white power group — attacks that took place just hours before the sentencing of the ex-cop who was convicted of his murder.

The two edifices struck had just been installed in Brooklyn’s East Flatbush neighborhood and outside of City Hall in Newark, N.J. to honor Floyd — whose videotaped murder by a then-Minneapolis police officer, Derek Chauvin, shocked the nation.

“Just days after its unveiling on Juneteenth, and a day before the sentencing of Floyd’s murderer, this defacing that appears connected to a White supremacy hate group may have been an attempt to strike terror into our community — and it should be investigated accordingly,” said Brooklyn Borough President Eric Adams, who called for federal law enforcement to get involved.

The front-runner in the recently completed Democratic mayoral primary released the statement through his government office.

Adams was joined by the two other top contenders in the race, Maya Wiley and Kathryn Garcia.

“The vandals responsible must be investigated and prosecuted to the fullest extent of the law,” said Garcia in a statement, who described the attack as “nothing short of a hate crime.”

“This is when we must stand up and say without hesitation that there is zero tolerance for hate in New York City,” she added.

Wiley tweeted her condemnation of the attack.

“Hate will never win,” she wrote. Thank you to everyone who is working to clean up this beautiful monument and to those working to bring the perpetrator of this hate to justice.”

Both statues were attacked early Thursday and tagged with slogans that link back to Patriot Front, which experts at the Southern Poverty Law Center describe as a white nationalist hate group that formed in the aftermath of shocking neo-Nazi protests in Charlottesville, Va., in 2017.

The New York City Police Department’s anti-hate crimes task force is already investigating the attack in Brooklyn and officials in Newark told the Star-Ledger that they are investigating the attack there.

Chauvin, 45, was found guilty of all three charges against him — second-degree murder, third-degree murder and second-degree manslaughter — on April 20. He was videotaped pressing his knee to Floyd’s neck on the ground for more than 9 minutes. The killing sparked nationwide protests and a push to “defund” police departments, which has been blamed for a spike in violent crimes across the nation.
