A community celebration in Bushwick ended on a somber note Sunday night—just hours after the neighborhood wrapped up its 7th annual Puerto Rican Day Parade.

Police say two teenage boys were stabbed around 8 p.m. near Suydam Street and Knickerbocker Avenue, right across from Maria Hernandez Park.

The parade itself ran from 3 to 5 p.m., and video shows crowds earlier in the day waving Puerto Rican flags, dancing, and enjoying music up and down Knickerbocker Avenue. It was a smaller, more local version of the larger Puerto Rican Day Parade held in Manhattan—but just as full of energy and pride.

Hours later, that same stretch of the block turned into a crime scene.

A 19-year-old was stabbed in the stomach, and an 18-year-old was stabbed in the back, according to the NYPD.

Both teens were rushed to Elmhurst Hospital. The 19-year-old remains in critical but stable condition. The 18-year-old is expected to be OK.

So far, no arrests have been made, and police haven’t said what led up to the stabbing. At this time, they have not confirmed any direct connection between the attack and the earlier parade.

Anyone with information is asked to call Crime Stoppers at 1-800-577-TIPS.
