ALESHA MacPhail’s killer is said to be 'bulking up’ in a prison gym out of fear that he will be attacked.

Aaron Campbell has begun punishing gym sessions at Polmont Young Offenders Institution ahead of his move to an adult prison.

Campbell, who raped and murdered six-year-old Alesha in 2018, turned 21 in May and is said to be terrified that he will "have a target on his back" when he moves. 

A source told the Scottish Sun: “He is bulking up because he knows when he gets to the adult prison, he will have a target on his back for what he did to that young girl.

“He has never shown any interest before in working out or being in the gym.

“But when he realised he would soon be moved to an adult jail he asked for access to the unit’s fitness centre. 

“Maybe he is worried he will need to be able to defend himself when he is moved.”

The Scottish Prison Service does not comment on individuals.
