Sgt. Sue Depoe, Det. Sgt. John Lynch and Officer Matt Carleo arrived at the undisclosed address around 1:30 p.m. Aug. 16, where the boy had been pulled from the pool by a teen lifeguard, authorities said.
Carleo began life saving measures on the child, and then officers performed CPR.
The boy's heart was restarted before he was taken to a local hospital, police said.
"The department commends these officers whose quick thinking and teamwork were able to save a child's life," authorities said in a statement.
