A gun-toting bicyclist opened fire in Crown Heights last night, wounding two teenagers, police sources said.

A 13-year-old boy was shot in the buttocks, and a 19-year-old was hit in the back about 8 p.m. on Crown Street near Ford Street, cops said.

They were listed in stable condition at Kings County Hospital.

A bike and a gun were recovered, sources said, but no arrests have been made yet.

During the investigation, a police source said a shot was fired at cops about 10 p.m. near Eastern Parkway, but a police spokesman said no shots were fired at or by police.

The shooter was described as wearing baggy black pants and a black hoodie.

Police ask anyone with information about last night’s violence to call Crime Stoppers at 1.800.577.TIPS.
