A 66-year-old visitor from the United States died on Sunday morning after snorkelling at Peter Island, Virgin Islands Search and Rescue confirmed.

The man, originally from New York, was touring the Virgin Islands onboard a charter boat along with his wife and other family members.

On Sunday, the group was moored in Great Harbour on their second day of vacation. The man went snorkelling and a short time later was seen floating in the water and non-responsive, according to VISAR rescue coordinator Phil Aspinall.

The captain of the charter boat called VISAR, pulled the man to shore, and performed CPR on the beach until rescuers arrived, Mr. Aspinall said.

VISAR crewmembers continued CPR as they transported the man back to Tortola, but the victim was pronounced dead at Peebles Hospital at about 11 a.m., Mr. Aspinall confirmed.

The cause of death has not been announced. Mr. Aspinall did not immediately release the name of the victim to protect the privacy of his family members.
