Man has throat slashed in scuffle outside Chelsea Piers gym, leaving pool of blood on sidewalk

A 53-year-old man had his throat slashed after getting into a beef with a second man outside a Brooklyn gym late Monday morning — with the accused slasher still on the loose, police said.

The violence erupted on the same block as Chelsea Piers Fitness gym on Schermerhorn Street around 10:45 am, when the victim and the assailant got into a dispute, an NYPD spokesperson said.
