A human bone washed up near the famous Jane’s Carousel on the waterfront in Downtown Brooklyn early Wednesday – two days after a park worker discovered more skeletal remains there, police said.

The bone – described as a human leg or part of it – was discovered by police officers around 12:20 a.m. on the banks of the East River on Water Street in DUMBO while responding to a 911 call, authorities said.

The horrifying discovery followed the discovery of a skull and bones in the same area on Monday morning, police said.

Those remains, discovered by a city park ranger, were covered with clothing, sources said.

According to sources, a pair of boots was also found nearby.

The NYPD said it was too early to determine whether there was a connection between the two gruesome discoveries.

The city coroner’s office is investigating.
