A 19-year-old has put himself in breach of a suspended sentence and could face going to prison after getting caught with a quantity of cannabis.
Leon Vertigan, of Priory Road in Downham, pleaded guilty to having the Class B drug in his possession while in Lynn.
Vertigan had been given a suspended sentence in Manchester Crown Court after intending to supply Class A drugs.
He will be sent to Norwich Crown Court for sentencing at a date yet to be decided.
Vertigan has been released on unconditional bail.
