In a second incidence of shark attack in the island waters of Seychelles, where the Duke and Duchess of Cambridge have had their honeymoon, a newlywed honeymooner was killed on Tuesday.

The victim, identified by his wife as Ian Redmond, was snorkeling off Anse Lazio beach on Praslin Island in the Indian Ocean when a 6-foot long rogue shark attacked, The Telegraph reported.

The 30-year old British tourist, who got married on August 6, screamed for help, while his wife Gemma Houghton, 27, watched helplessly from the shore.

Praslin is one of the most visited spots in Seychelles and such an incidence within a fortnight is feared to affect Seychelles' tourism, which got a boost post the popularity for being the Royal honeymoon destination of Prince William and Catherine Middleton, according to travel experts.

William and Kate spent their honeymoon at one of the world’s most popular spots for newlyweds, the North Island, just 30 miles away from Praslin Island, where the attack happened.

On August 2, a 36-year old French diver was killed in a fatal shark attack on the same beach, which according to Seychelles Tourism Board, was the first in waters around Seychelles in the last 50 years.

The authorities have banned swimming and any water activities in the areas surrounding the site of accident and have called shark experts to track down the attacking sharks.
