The tourism authorities in the Seychelles where a British honeymooner died in a shark attack have admitted that tourists may not have had adequate warnings, according to reports.

30-year-old Ian Redmond was snorkelling off Anse Lazio beach during his honeymoon, when he was fatally bitten by what is thought to be a great white shark.

Alain St Ange, the director of Seychelles Tourism Board, revealed: “The beach was manned by police. They tried to get as many people as possible to say: ‘please don’t go into the sea or stay at knee-depth’, where the sharks would not be.

“We did try. Maybe not enough. Maybe we should have done more”

Mr Redmond, an IT specialist, was killed 10 days after his wedding to Gemma Houghton at St Michael’s Church in Dalton, Lancashire, near the bride’s family home.

Less than a month ago a French tourist was killed in a shark attack in waters off Praslin.

Government officials have issued a ban on swimming in certain areas until the killer shark is captured. The Navy have been called to help catch the shark and local fishermen have been joining the search.

The Seychelles archipelago of 115 islands in the Indian Ocean is one of the most popular honeymoon destinations worldwide.
