A 16-year-old boy was hospitalized after being hit by a car on Front Street near Tioga in Kensington.
The driver initially fled the scene because witnesses tried attacking him, police spokeswoman Tanya Little said. The man drove to a safe location where he called police to report the accident.
Little said the boy was playing in the street at about 7:20 p.m. when he was hit.
Medics took the boy to nearby St. Christopher's Hospital for Children, and police said he appeared to suffer from head injuries.
