A grieving Scots dad has opened up on the heartbreak of losing his teenage son to an undiagnosed heart condition and has said that there were "no warning signs" prior to his death.
Cristopher Cowe, from Edinburgh, was just 15 when he passed away from myocarditis - which is a rare cardiovascular disease that can reduce the heart's ability to pump and cause rapid or irregular heartbeats.
His dad, Ross, said that he displayed no symptoms before he died just weeks before his 16th birthday.
