Humberside Police have named a diver whose body was recovered off the Donegal coast as one of their officers, Pc Paul Jackson, 49.
Pc Jackson died off the Donegal coast
He had been on holiday at the weekend when he failed to surface from a dive.
Two lifeboats, two helicopters and other vessels were involved in the search for the officer.
Pc Jackson, who served with Humberside Police for nearly 25 years, was one of seven people deep-sea diving 16 miles (26km) north-northwest of Horn Head.
He is believed to have been using an oxygen set known as a rebreather which provides a breathing gas containing oxygen and recycles exhaled gas.
His family - partner Christine, mother Beryl, brothers Tony and Derek and sister Teresa - issued a joint statement:
"Paul died diving, a sport he loved, in Ireland, a place he loved.
"We would like to pass on our immense thanks and gratitude to all of the emergency services and volunteers who helped to find him and ensure he could be laid to rest, and especially to those people that were his friends for all they did to bring him home.
"Paul was a fun-loving man who loved life and loved his family, and he will be missed dearly by everyone who had the pleasure of knowing him."
