A bank manager who sketched plans for her boyfriend to carry out a 400,000-pound raid at her former branch cried as she was led to the cells after being convicted of robbery.

Rachael Shariar-Namini, 23, was told by Judge Sally Cahill QC she could face a substantial prison sentence after a jury returned a majority verdict on Monday.

During the four-day trial the court heard how Shariar-Namini provided the inside information for boyfriend William Wormald, 26, during a night out.

He and Darren Ashcroft, 38, used the knowledge to climb into toilets through the first floor roof before carrying out the robbery at the NatWest branch in Hunslet, Leeds, West Yorks., on March 9.

The masked men, one with a crowbar, took 371,691 pounds in cash which was in temporary storage awaiting collection by a Securicor van.

The court heard how a plan of the bank was found at Ashcroft's home after the raid.

Wormald, Ashcroft and David Cowie, 32, who provided a getaway car, had already admitted robbery. All four will be sentenced at a later date.
