It began in the 1600 block of South Corlies Street just after 4:00 p.m. Monday.
Investigators say a detective from the Southwest Division and an officer from the Attorney General's Office were driving through the neighborhood on their way to serve a warrant when they saw a 16-year-old carrying a rifle on the street:
"The detective exited the vehicle, approached this male, and ordered him to drop the weapon. The suspect then pointed the rifle at the detective. The detective then discharged his weapon," Philadelphia Police Chief Inspector Scott Small said.
The shot missed the teenager who then dropped the rifle and ran through the neighborhood.
Investigators say, in an effort to cut him off, the officer from the Attorney General's Office drove his car the wrong way on Corlies and accidentally crashed into a Cadillac passing by on Tasker Street.
The 60-year-old driver and his teenage passenger suffered minor injuries and were taken to a hospital for treatment.
"We had a real good description of the suspect and about a half hour to 45 minutes later, police did apprehend the suspect in the area of 26th and Dickinson. Officers positively identified the suspect as the male who had the weapon and pointed the weapon at the detective," Small said.
As is routine whenever an officer fires a weapon, Internal Affairs is investigating the incident.
Meanwhile, the 16-year-old, who was not injured, was being questioned by investigators as to what he was doing walking on the street with a rifle.
He faces a number of very serious charges for pointing a weapon at an officer of the law.
