Police believe Yermia Yunataev was strangled

Yermia Yunataev, thought to have been in his 40s, was killed in a room on the seventh floor of the Marriott Hotel last Sunday.

His body was discovered after bloody clothes and documents were found dumped at a Eurotunnel terminal in Kent.

Post-mortem tests failed to establish how he died but police believe he was probably strangled or suffocated.

They are investigating the possibility that he was the victim of a "hit" carried out by an international drug or organised crime gang.

Detectives said Mr Yunataev was believed to have had an Israeli passport, although he is also thought to have checked into the hotel under a false name.

Police said he arrived at the hotel at 0905 BST on Sunday in a black cab and went into the bar area until 0950 BST before going to the hotel lift.

A police spokesman said: "We need to speak with anyone who knew Mr Yunataev."

Police are also keen to trace the driver of the black cab which dropped him at the hotel.
