Rescue teams were unable to reach the injured man to offer treatment and requested emergency airborne support, which was supplied by the coastguard helicopter operating out of Prestwick in Scotland.
The victim was last night receiving treatment in Altnagelvin, where his condition was described as serious, but not life-threatening.

Fortunately, the swimmer involved was quickly located and the rescue operation was wound down.
