A 14-year-old boy has been apprehended and 18-year-old man is already in custody after, officials said, a fight on a SEPTA bus in Philly’s Frankford section erupted into a shooting when the pair exited the bus.

In an update released Saturday, police officials said, officers were about to track down a 14-year-old boy who was sought following a shootout that occurred at about 5 p.m. on Friday, at the intersection on Frankford and Kensington avenues.

During the incident, officials said, a fight between the 14-year-old and an 18-year-old man began on the Route 3 bus.

Once the bus reached the intersection of Frankford and Kensington avenue, officials said, one of the individuals involved in the altercation exited the bus through a rear door and produced a handgun and fired at the bus.

At that same time, police said, the other individual apprehended in this incident was exiting the bus and returned fire.

No one was struck by gunfire during this incident, officials said. But, a bullet was fired into the bus and a bullet hole could be seen in a window of the vehicle shortly after the shooting.
