A poison map of London
In 2006 ex-FSB Officer Alexander Litvinenko was poisoned using the highly radioctive Polonium-210.
But in the process of poisoning Litvinenko, his two assassins, Dmitri Kovtun and Andrei Lugovoi, left a radioactive trail across London that would prove critical in solving the murder of Alexander Litvinenko.
Here are some of the Central London locations that were found to contain traces of Polonium-210.
1. 25 Grosvenor Street
Where Kovtun and Lugovoi met Alexander Litvinenko after arriving in London.
2. Milennium Hotel
Where Alexander Litvinenko met associates shortly before he became ill. It was here that he unknowingly consumed the fatal dose of poison which was placed into his green tea on 1 November 2006.
3. Sheraton Grand Park Lane hotel
Where Lugovoi stayed during one of his three visits to London – and disposed of the poison down the sink. The levels of radiation later found on the towel which he used to mop up some of the poison were so high that it was sent to the Atomic Weapons Establishment at Aldermaston.
4. Itsu restaurant
Where Kovtun, Lugovoi and Alexander ate after their first meeting.
5. HeyJo nightclub
Lugovoi and Kovtun spent three hours here before leaving at 3am. Radiation was found in one of the cubicles, in the restaurant and in the gents’ toilets.
6. Dar Marrakesh
After eating with Alexander Litvinenko at Itsu, Lugovoi and Kovtun visited this bar – radiation was found on the shisha pipe which Lugovoi was thought to have smoked on the terrace.
7. 1 Cavendish Place
The base of the security firm ‘Risc Management’ visited by Alexander Litvinenko, Kovtun and Lugovoi on 17 October 2006.
8. Pescatori restaurant
Where Lugovoi is understood to have dined before the fatal poisoning on 1 November 2006.
9. Best Western Shaftesbury Avenue
Where Kovtun and Lugovoi stayed when they first arrived in London with the intention of poisoning Alexander Litvinenko.
10. University College Hospital
Where Alexander Litvinenko died on 23 November 2006.
