Sentencing of an armed robbery gang whose crime spree included a bank raid in Oxford is due to begin today.

The gang of seven carried out 18 raids on security vans making cash deliveries to banks across the country in 2006 and 2007.

Their spree included a raid on the HSBC bank in Summertown, Oxford, in November 2006.

They were caught when a police marksman shot ringleader Mark Nunes and accomplice Andrew Markland dead during a foiled raid in Chandler's Ford, Hampshire.

Getaway driver Terence Wallace, 26, and other gang members Adrian Johnson, 28, Leroy Wilkinson, 29, and Victor Iniodu, 34, all from south London, were found guilty of conspiracy to rob earlier this month following a seven-week trial at Kingston Crown Court.

Three other men - Leroy Hall, Leon McKenzie and Brian Henry - pleaded guilty to being part of Nunes' gang before the trial began.

The trial heard some of the raids were carried out with guns and the robbers used violence against guards if they would not hand over their cash boxes.

But the jury heard that Nunes' "luck ran out" when he was gunned down as he held a pistol to the head of a security guard close to a branch of HSBC in Chandler's Ford.

The whole gang are due before Kingston Crown Court at 10.30am today for a sentence hearing which is expected to end on Monday.
