Police hunting the attacker of a wealthy Russian banker shot in a suspected assassination attempt have appealed for a taxi driver to come forward.
The cabbie took German Gorbuntsov to his home shortly before he was shot and it is thought he may still have been in the area when the crime took place.
Mr Gorbuntsov remains "critical but stable" under armed guard in hospital after he was shot several times as he entered his multimillion-pound executive apartment near Canary Wharf, east London.
