More than 500 people have joined the search for a British man missing in the Cayman Islands. Nathan Clarke, originally from Cheltenham, was last seen a week ago on Grand Cayman.

His phone was found in the sea and a search of the water began yesterday along the Seven Mile Beach area with 527 volunteers and 39 police officers joining the hunt on the Caribbean island.

Mr Clarke works as a teaching assistant on Grand Cayman and has lived there for about four years. The 30-year-old was last seen near Calico Jack's beach bar on West Bay Road on 25 February.

His parents, brother and sister are understood to have arrived on the island yesterday.
