The family of missing teenager Andrew Gosden will hold a vigil at Doncaster train station to mark the ten year anniversary of his disappearance.
The vigil it set to take place on Thursday 14th September at 4pm.
Andrew's father Kevin Gosden is holding a sponsored silence to mark the occasion.

He wants to raise money for the charity Missing People, who have helped the Gosden family with their campaign to find their son in the last decade.
The Missing People charity are also holding a minute of silence by the memory tree in London as part of a national service to remember all those who are missing across the country and further afield.

Detective Chief Inspector Joanne Bates said: “Andrew was 14-years-old when he went missing, and there has been no contact or positive sightings of him since this time".
She added: “I would ask anyone, maybe new friends, neighbours or work mates, who believes they know a 24-year-old man that could be Andrew, but aren’t aware of his past beyond the last few years to please make come forward.
“In addition, any professionals, including doctors, dentists or hospital staff who may have treated a 24-year-old man who has no records going back beyond the last ten years, you could hold information that proves vital to locating Andrew and I would ask you to please make contact with police.
“And to Andrew, a personal appeal, please contact us, completely confidentially, and let us know you are safe and well and we can reassure your family you have come to no harm.”
