Mason Price was a member of the gang known as the Dale Sken Crew (DSC). After being released from a Young Offenders Institution, he, Tariq Siddiqui and Kyle Stack tagged (with the DSC logo) and vandalised parts of the school. Daniel Chalk had his classroom vandalised after Mason persuaded Tariq that Chalky spoke to him disrespectfully. The school canteen was also vandalised.
After Mason asked other DSC members for a knife, he persuaded Tariq to attack Finn Sharkey because of Finn's relationship with Tariq's sister, Trudi Siddiqui.
Daniel was made aware of these plans and intervened, which resulted in Mason being arrested again for knife crime. No other members of the DSC were arrested.
Following Mason's arrest, Kyle revealed to Tariq that Mason was "all mouth" and that he wasn't really friends with him.
Mason is not seen again.
