The parents of a teenager who was found dead in Heywood have paid tribute to their "unforgettable" son.

Callum Riley, 17, was found with serious injuries on Atholl Drive on Saturday and died shortly afterwards.

On Sunday, a 25-year-old man was arrested on suspicion of murder and a 23-year-old woman was arrested on suspicion of assisting an offender.

They remain in police custody alongside two men, aged 18 and 33, who were arrested on Saturday.

A 21-year-old woman has been released and faces no further action.

His mum said: "Callum was a strong and caring young man, loved so deeply by his family, friends and his girlfriend.

“His love for his mother and his brothers was immeasurable.

“A lovely lad, with a good heart, protective of his family and always the best of intentions. Stolen away from us far too young in life.

“He will be forever missed, and remembered with love. Life will never be the same again.

“As a family we ask for the respect and privacy whilst we come to terms with this huge loss in our lives."
