On Memorial Day, Fairfax County Police used Crisis Intervention Training techniques to try communicating with a distressed 20-year-old lifeguard at the Riverside Park Swimming Pool.

Police said officers received a call about the emotional lifeguard around 1:30 p.m. The man ignored their attempts to talk with him.

Police evacuated the pool, after which the lifeguard jumped into the pool, swam, got out and talked loudly. He only spoke Polish, Police said.

An officer who speaks Polish was called to the scene, but the lifeguard continued to refuse to communicate.

He jumped back in the pool and went down to the bottom. Another Riverside Park lifeguard and additional officers brought him back to the surface. He was unresponsive.

The emotionally distressed lifeguard regained consciousness with help from members of Fairfax County Fire & Rescue. Then he became combative, police said.

Police took the man into custody and then to Inova Fairfax Hospital. He was in a non-life-threatening condition. He was set to be evaluated there.
