A mile-long island has emerged from the sea in the mysterious Bermuda Triangle and thrill seekers are being told to stay away from it.

Axar.az reports citing Newsweek.

The mile-long sand bank has appeared in the North Atlantic Ocean over the last couple of months, but people are being told to stay away from the new land because of strong currents in the gap separating the sandbank from the mainland.

The island - which can be found just off Cape Point in North Carolina - has been nicknamed Shelly Island by locals due to the large number of shells found upon it.

Janice Regan told PilotOnline of the sand bank: "Yeah, isn't it crazy? It was just a little bump in April."

Despite rapidly becoming a tourist attraction, people are being told to keep clear of the island as although the distance between the two is just 50 yards, the riptides are said to be incredibly strong.

And as Bill Smith, president of the North Carolina Beach Buggy Association admits, there's also a concern surrounding sharks in the waters.

He said: "We're worried about shark bites, but we're more worried about drownings."

The future of the island is not clear as the sand bank could continue to grow or could vanish.
