FOUR teenagers from Pinner could be jailed this week for their part in a graffiti spree which caused up to £75,000 damage to train carriages on the London Underground.

The boys painted their tag, 'FTS', on numerous Metropolitan Line trains between April 2008 and June 2009 in what is thought to be a crude protest against the capitalist and political system.

Richard Borgonon and Jack Browne, both 18, Elistar Filardi, 19, and a 17-year-old who cannot be named for legal reasons will be sentenced at Southwark Crown Court tomorrow (Friday) alongside two other 17-year-olds from Hampstead and South Oxhey.

The group has already admitted conspiracy to commit criminal damage.

The cost of the damage caused to trains running between Watford and Wembley, Watford and Harrow and overground trains between Amersham and Baker Street was between £70,000 and £75,000.

Currently on bail, the boys could be given anti-social behaviour orders in addition to any jail sentences.

The results of a pre-sentence report will determine whether Borgonon, of Cannon Lane, Browne, of Somerford Close, Filardi, of Pinner Road, and the three 17-year-olds will go to prison, and for how long.
