Guide-line death diver named after wreck tragedy.
Mr Anslow was on a chartered boat with a party of divers to dive to a wreck off the coast of Beadnell, Northumberland, on Friday.
The 51-year-old had completed his dive but got into difficulties when he was following a guide line back.
An extensive search involving local boats, the Seahouses inshore lifeboat and helicopters from RAF Boulmer was launched when he slipped beneath the water and failed to re-emerge.
He was later found in the water and airlifted to Wansbeck Hospital, in Ashington, but despite extensive efforts to resuscitate him he was pronounced dead at the hospital.
The incident is now being investigated by Northumbria Police's marine unit.
