A 14-year-old youth was stabbed to death in the Bronx early Sunday morning and three other teens also were injured, police said.

NYPD officers found the teen stabbed in the chest about 3:15 a.m. near the 2100 block of Barnes Avenue.

Two 18-year-old men were stabbed in the chest and a 17-year-old was stabbed in the shoulder, NYPD detectives said.

Paramedics took the four teens by ambulance to Jacobi Medical Center, where the 14-year-old was pronounced dead. The three other teens were being treated for their injuries, but their conditions were not available.

The 14-year-old's identity has not been released pending notification of relatives.

No arrests have been made.

Police have not said what prompted the stabbing.
