A boy was hospitalized Saturday after nearly drowning at Six Flags America in Prince George's County, authorities said.
First responders were called to Six Flags America in Largo “for a working CPR call,” at about 4:40 p.m., the Prince George's County Fire Department said.
County police said the child, who was under 10 years old, slipped into the wave pool and was underwater and unconscious for several minutes.
The boy was discovered by swimmers at the pool and was pulled from the water by lifeguards who immediately began CPR, police said.
Off-duty officers, who were working security, rushed the child to the first aid station, where they continued life-saving efforts, police said.
The boy was taken to Children's National Medical Center in D.C. with serious injuries, authorities said.
Police said at one point that they were able to recover the child's pulse and he was in stable condition.
It was unclear how the child slipped into the large pool called Hurricane Bay. It's described by the amusement park as a pool that generates ocean-size waves.
A Six Flags America spokesman said in a statement: "The safety of our guests is always our highest priority. Earlier today, our certified lifeguards and First Aid team assisted a guest in the waterpark who was showing signs of distress. The guest was transported to a local hospital for further evaluation and treatment. We are pleased our lifeguards were able to utilize their training to offer lifesaving measures and we send our best to the guest and his family."
