Two young men involved in a bank raid that netted £25,000 have been locked up for a total of four years and three months, while a third must carry out 100 hours unpaid work.

The trio were said to have been "tutored" by older gang members who had already stolen more than £90,000 during a series of robberies on security guards as they delivered cash to banks in the summer of 2009.

Jeton Nushi was just 18 when he acted as a look-out for the robbery at Lloyds TSB in Sheerness High Street in August 2010.

Maidstone Crown Court heard a Group 4 driver was delivering cash when he was pushed and the moneybag snatched.

The gang fled in a stolen BMW parked nearby in a car park in Trinity Road.

Nushi, of Barlby Road, west London, admitted robbery, while Harriboy Disson, 18, from Kensington, west London, and Ashley Jarman, 20, of Langdale Close, Rainham, admitted handling the stolen BMW.

Dale Sullivan, prosecuting, said Disson - who was 16 at the time - acted as "a link" between his co-defendants and Sheerness father-and-son Peter Clarkson and Peter Clarkson Jnr.

The Clarksons were each jailed last year for 14 years after being convicted of conspiracy to rob NatWest and HSBC in Sheerness, HSBC in Bexleyheath, Lloyds TSB in Sidcup and Lloyds TSB in Redhill, Surrey.

Disson later admitted three of the five "cash in transit" robberies and was sentenced to a 12-month detention and training order last year.

The court was told at the time of the raid on August 27 2010, Peter Clarkson Snr, 56, of Hartlip Close, and his 34-year-old son, of Mills Close, Minster, were in custody awaiting trial.

However, Mr Sullivan described it as being "within the style of the Clarkson robberies", involving the use of a stolen BMW and delivering "a short, sharp shock" to the security van driver.

"The Crown put the Clarksons as the tutors of the younger group of criminals," he explained.

Disson denied robbery at Lloyds TSB in Sheerness and the charge was left on file. However, he admitted a second offence of handling a stolen BMW and dangerous driving in Herne Bay in September 2010.

No evidence was offered against Jarman in relation to the Lloyds TSB robbery. But he admitted converting criminal property by using £3,800 of the money stolen in the raid to buy a Vauxhall Astra in Leysdown the following day.

Nushi also admitted two offences of burglary and asked for 14 further burglaries - all committed in London and Hertfordshire - to be taken into consideration. He was sentenced to a total of three years and three months in a young offenders' institution.

Disson, currently serving four years for an unrelated robbery, was locked up for 12 months. However, his sentence will not affect his earliest release date of January 27 next year.

Jarman was sentenced to a community order with 100 hours unpaid work and 12 months supervision. He must also attend a Home Office-accredited "thinking skills" programme.

The court heard none of the £25,000 stolen has been recovered.
