The discovery in Sheepshead Bay on Monday of a man’s body wrapped in black plastic bags, his feet set in cement and his hands bound behind his back, rekindled memories among some law enforcement officials of old-time mob executions in New York City.

“It was old school,” NYPD Chief of Detectives Robert Boyce said Tuesday about the way the body was disposed of. “We are treating it as a homicide.”

Late Tuesday, police were able to tentatively identify the victim but were waiting to notify his family before releasing his name.

A law enforcement official said the body was that of a 28-year-old Brooklyn man with a lengthy criminal record and a gang affiliation.

The family has not yet been notified. The feet of the man were in a bucket filled with cement but the weight was not enough to keep the body submerged, the official said.

The man was believed to be the victim of a possible drug dispute, law enforcement officials said.

According to Boyce, the body was discovered by a student about 10:30 a.m. Monday in the water in Canarsie, Brooklyn. Boyce estimated the body had been in the water up to two weeks. The victim’s fingertips were missing, likely because of animal activity, he said, adding that the medical examiner was conducting an autopsy to determine the cause of death.
