**UPDATE:** The boy was officially pronounced dead.
A teenage boy is fighting for his life in a Monmouth County Hospital after he was discovered at the bottom of a lagoon during a day of swimming in Brick Township on Saturday evening.
According to a statement released by police, at approximately 6 pm, officers were dispatched to 58 Toronto Drive in reference to a report of a 15-years-old male who was unconscious and unresponsive at that location.
Emergency responders arrived at the scene and learned that the juvenile had been swimming in the lagoon located in the rear of a residence with several other friends.
Police say, when the group began to swim and jump into the water, one of the male juveniles apparently went under and did not resurface.
According to police, after approximately five minutes inside the lagoon, someone noticed that the juvenile was not with the group and several people began a search.
Police say after several dives, the homeowner located the boy towards the bottom of the lagoon where he then pulled him out and placed him into a boat. The homeowner immediately attempted to revive the juvenile with life-saving techniques police said.
Police, EMTs and Paramedics arrived on the scene and continued the life-saving efforts according to authorities.
Police say EMS transported the juvenile to Jersey Shore Medical Center via ambulance where officials say they could not confirm his condition.
The incident remains under investigation.
