An internal NYPD alert warned officers of containers of hardened concrete resembling “chocolate chip ice cream” found near the scene of a recent George Floyd protest in Lower Manhattan.

Three containers of the alleged hard serve — poured into what appear to be to-go coffee and soup cups and flecked with darker-colored spots — were found sitting on a window ledge near the Worth Street entrance to Manhattan Supreme Court on June 3, according to the memo obtained by The Post.

“The Cups were filled with cement and made to look like CHOCOLATE CHIP ICE CREAM,” the alert read in part.

There were no immediate reports of the improvised weapons being used against cops, but the NYPD was nevertheless ordered to be on guard for them.

The department has also warned of concrete-filled tennis balls and water bottles, and Commissioner Dermot Shea has said that looters are strategically stashing bricks prior to protests.
