A county scout master has been jailed for 18 years after pleading guilty to 49 child sex offences involving nine victims.
37-year-old David Sewell, of Valley Road, Grantham, pleaded guilty to the charges, including the rape of a boy under the age of 13, sexual assault of boys under the age of 13, sexual touching, voyeurism and the possession of child sex abuse images.
Lincolnshire Police's investigation into Sewell, whose youngest victim was just 10 at the time of his offending, was prompted when a local man reported historic sexual assaults to officers in July this year.
Supt Rick Hatton, Head of Lincolnshire Police's Public Protection Unit, said: "Sewell is a very dangerous predatory paedophile and his crimes have had a profound and lasting impact on several young people's lives.
"The systematic and planned grooming of these young people illustrated the calculated and manipulative offending of Sewell, who placed himself in positions where he had access to children and could gain their trust.
"We hope that Sewell's conviction helps them, in some sense, to move forward with their lives. Lincolnshire Police and our partners in Social Services will continue to offer the families involved as much support as possible."
Police searching for missing sex offender Geoffrey Ball have received several reports of sightings of a man believed to be him in the Whitby area.
The most recent sighting was May 21 in the town centre area. It is believed he was wearing a navy blue hooded top, blue jeans and white trainers. He has also been seen in a black padded jacket.
Detective Inspector Kath Barber from Cleveland Police’s Public Protection Unit said: “Officers are concerned as to the methods he may use to obtain cash to travel further. Police would ask members of the public to be aware of requests for cash from people not known to them personally.
"We are not sure of where he might be staying. He could be using hotels or B&Bs. “Mr Ball has got previous convictions for violence which is why we would advise members of the public if they see him, not to approach him, but to call police immediately on 999.
“I would particularly urge people to be vigilant around social media sites as he uses them to make contact with people he doesn’t know.”
