John, who is from the Woodlands area, was 37 when he was reported missing in January 1993 having not been seen since July 1992.

An investigation into his disappearance was launched, with several reviews taking place over the years and following a recent review by our Major Crime Unit, two people have today (Monday 6 October) been arrested.

Senior Investigating Officer, Detective Chief Inspector Benjamin Wood said: "This morning, we have carried out searches at three addresses in Barnsley, Goole and Buxton.

"Two men, aged 64 and 72, have been arrested on suspicion of murder in connection with the disappearance of John. They remain in police custody at this time.

"As part of our investigation, we are also carrying out searches of Ulceby Vale Quarry in North Lincolnshire and there is likely to be an ongoing police presence at this location for the next few days.

"John is a dad-of-three and now a grandfather to two children. His family have been informed of this latest development and they remain at the forefront of our minds as we progress our enquiries.

"They are desperate for answers and as we release this new information along with a picture of John, we hope it will jog people's memories of the case and encourage anyone who may be able to help us with our investigation into his disappearance to please get in touch.

"Any information you can provide, no matter how insignificant it may seem, could prove crucial and for the sake of John's family I would urge you to please contact us.

"We are very grateful to those who contacted us at the time of his disappearance but if you didn't and have information which you think may be useful, please do not hesitate to get in touch with us."
