The "devastated" family of a boy found dead on the M9 have made an appeal for information about his death.

Michael Easton, 13, has been described as a "quiet and well-behaved boy" by his family after he was found on the westbound carriageway of the M9, between junction 5 and junction 6 at 5.40am yesterday.

He was last seen at 9.50pm on Friday in Grangemouth town centre and was expected at his home in the nearby town of Polmont in Falkirk around around that time.

His family have asked anyone who may have information about what happened to Michael to contact the police.

In a statement the family said: "We have all been left utterly devastated by the death of our beloved Michael and are still trying to come to terms with our loss.

"Michael was a quiet and well-behaved boy, who never caused any trouble and who would have helped anybody. He loved his family deeply.

"He was a popular young boy who had a keen interest in biking. One of his prized possessions was his scooter and he and his friends spent several hours each week riding around Grangemouth.

"It is difficult not knowing exactly what happened to Michael and we would ask that anyone who knows anything that can help the police with their investigation to pick up the phone.

"We would finally like to thank everyone for all of their kind words and messages of support at this very difficult time. It means a great deal to us all and shows how fond the local community was of Michael.

"However, we would now ask our privacy be respected to grieve for our son, brother and friend."

Anyone with information relating to this incident have been asked to contact Police Scotland on 101 or anonymously via Crimestoppers on 0800 555 111.
