A teenage Harry Potter star is facing jail after police reportedly found cannabis growing in his bedroom.
Jamie Waylett, who has played Hogwarts bully Vincent Crabbe in six films, was allegedly caught with eight bags of marijuana in his car after a police tip-off.
Drug squad officers then raided the 19-year-old's parent's home to allegedly discover ten mature plants in his bedroom.
The dope, which was reportedly growing under hydroponic lights alongside the teen's PlayStation and DJ decks, was valued at about $4100, The Sun reports.
Waylett and a friend riding in his Audi, also 19, were held on suspicion of possession and production of a Class B drug.
If convicted, the offences carry a maximum jail term of five and 14 years.
It's not the first time the London actor has been linked to illegal substances.
In 2006, a video obtained by a British newspaper allegedly showed Waylett snorting cocaine.
He also reportedly bragged about getting high at a Harry Potter premiere and invited strippers back to his flat.
Both teenagers were bailed until July pending further enquiries.
