A local fisherman helped to save a man's life in Dublin Bay today.

Dun Laoghaire RNLI was called for assistance at about 4pm after the man's boat capsized and he was in the sea, near Dalkey.

When they arrived, a local fisherman was keeping him afloat from his boat, with the aid of a boat-hook.

Later, the man was given casualty-care on shore and was brought to St Vincent's Hospital for further treatment.

He's understood to be in a stable condition.

The Irish Coast Guard helicopter, Rescue 116, were also involved in this afternoon's rescue.
