Stephen Rex Brown The sidewalk outside Fine Fare was a bloody mess Sunday morning.

Wondering why there was pool of blood outside the Fine Fare on Avenue C Sunday morning? Here’s your answer: One of the men injured during Saturday night’s stabbing in East River Park was arrested outside of the grocery store.

The neighborhood’s top police officer, Deputy Inspector John Cappelmann (he was promoted from captain last week) confirmed the sequence of events, saying that the perp fled the park and was found at Avenue C and East Fourth Street. Initially, the police reported that only the suspect found at Fine Fare was arrested, but Inspector Cappelmann revealed that the 59-year-old “victim” ended up in handcuffs, as well.

“It was two people who are acquaintances. They got in a dispute in the park, wound up assaulting each other and both were charged,” Inspector Cappelmann said.

Meanwhile the blood, which was a hot topic of discussion on EV Grieve and Gothamist, has washed away in the rain.
