The body of a male juvenile was recovered from the pool at the Folcroft Swim Club, in Folcroft, Pennsylvania early Wednesday, Aug. 21.
Emergency crews were called to the pool on the 1900 block of Warwick Avenue just before 1 a.m. for reports of a drowning.
Police believed that four youths had entered the club after it closed.
The juveniles were diving off the diving board into the deep end of the pool when one landed on top of another swimming in the deep end, causing injuries, according to investigators, 6abc Action News reported.
