Police in Tennessee are searching for a suspect who shot an officer three times.

Chattanooga Police Department spokeswoman Elisa Myzal says at least one of the shots Thursday hit the officer in the arm, and none of his injuries are life-threatening.

Police Chief Fred Fletcher says the officer was shot while checking to see if someone was squatting in an abandoned building.

Myzel says authorities are using helicopters and drones to try to find the suspect, who Fletcher said could be armed and dangerous.
