KRABI: A 40-year-old German tourist was found dead in a room at a hotel in Ao Nang district of this southern province with a plastic bag covering his head and tied around his neck.

The tourist was found dead on the bed in a room on the sixth floor of the luxury hotel on Tuesday afternoon, said police.

The man's name was withheld pending notification of relatives. Dressed in shorts and a long-sleeved shirt,  the man's head was covered by a green plastic bag fixed to his neck with duct tape. They believed he had died one or two days earlier.
