Teens on motorcycle crash in Brooklyn during chase, 1 stabbed by driver, the other critically hurt

Two teens on a motorcycle crashed in Brooklyn, with one then stabbed by a driver who had been chasing them, police said Thursday.

The 17-year-old boy stabbed in the back was taken to Brookdale University Hospital in stable condition.

The 18-year-old man who was operating the motorcycle is in critical condition at the same hospital from head and body injuries he suffered during the crash, cops said.

The teens were zipping west on Highland Blvd. in Cypress Hills when they crashed and were ejected near Miller Place about 9:40 p.m. Monday — giving their pursuer enough time to get out of his black Honda sedan and stab the younger teen, officials said.

The attacker sped off in the Honda west on Highland Blvd. and has not been caught.

The NYPD released grainy surveillance footage of the suspect Thursday and asked the public’s help identifying him and tracking him down.

Anyone with information is asked to call Crime Stoppers at (800) 577-TIPS. All calls will be kept confidential.
