BALTIMORE (AP) — Police in Baltimore say four people were injured and three suspects were arrested following a shooting on the city’s east side.

The Baltimore Sun reports the shooting Friday left a crime scene that stretched nearly half a mile (805 m).

Police say the two men and two women who suffered gunshot wounds were taken to area hospitals for treatment. Their condition was not released.

Police say they were alerted to the shooting by a system that detects when a gun has been fired.
The police department urged anyone with information about what happened to call detectives.
