A Philadelphia police sergeant patrolling North Philadelphia by bicycle shot a man armed with a stolen gun overnight.
The unidentified sergeant spotted a man with a gun in his hand on the sidewalk along the 2500 block of North Alder Street just after 11 p.m., police said.
The sergeant got off his bike and demanded the man "drop the gun" but the gunman ran off through an alley, investigators said.
The sergeant gave chase and when he raised his flashlight to the suspect he saw the gun pointed at him, police said.
The officer fired four shots, striking the suspect in the right side and leg. Officers rushed the man to Temple University Hospital in Critical then stable condition, police said.
Investigators recovered the suspect's semi-automatic pistol loaded with 10 rounds, police said. The loaded gun was reported stolen in October from Clearfield, Pennsylvania.
Police confirmed that there was a large group of people assembled nearby but no one else was hurt.
