Pink Floyd rocker David Gilmour's incarcerated son is facing an inquiry by prison bosses after allegedly smuggling $4.80 (£3) into jail.
Charlie Gilmour was sentenced to 16 months in jail after he was caught on camera rampaging across London with fellow students last December (10) in protests against a huge hike in U.K. university tuition fees.
The 21 year old, who was seen swinging from a flag pole on the Cenotaph war memorial and urging fellow protesters to "storm Parliament", admitted to a charge of violent disorder and was ordered to serve time.
He is now in hot water again after he was caught with three £1 coins on his person following a visit, according to Britain's Daily Mail. The publication's editors report that Gilmour could be punished by having his books and possessions confiscated and the act could even affect his parole date.
A source tells the newspaper, "Gilmour was searched after he left an hour-long visit and three £1 coins were found in his pocket. Gilmour was clean when he went in - and had the coins when he left. It is believed they were passed to him during the visit.
"It might not seem a lot of money, but £3 goes a long way in prison and could be used to buy illegal items."
A Ministry of Justice spokesman says, "Prisoners are liable to adjudication if they are found in possession of illicit items."
