Police appeal to convicted fraudster in search for girl, 14 Link to video: Missing Lorna Vickerage's father appeals to daughter to make contact Police have appealed to a convicted fraudster who is believed to be with a missing 14-year-old girl to contact officers. Lorna Vickerage disappeared on Monday and is thought to be with John Bush, 35, who is a family friend. Both are from the north Doncaster area of South Yorkshire. Detective Chief Inspector Craig Robinson, of South Yorkshire police, told ITV's Daybreak programme: "We've still had no contact from Lorna or John Bush. We are doing both covert and overt work to track these people. We would appeal to John, if you are watching this bulletin, can you please make contact with police, and Lorna you are not in trouble, can you please make contact with the police? He added: "John's a family friend, I would probably suggest he has coerced her into going away with him. I don't think she is in any immediate danger from John but obviously she is at some sort of risk in terms of being away from her family, being in the company of an older man who might manipulate her. Robinson described Lorna as "quite vulnerable." She had been in the care of the local authority and was put in foster care on Friday. Lorna's family have also appealed for her to come home. Her mother, Christine, 36, wrote on Facebook on Thursday: "my baby plz come home darling we love u so much." Lorna was seen at 2.30pm on Monday at Outwood Academy in Adwick wearing her school uniform. She was spotted again on Wednesday morning, officers said. Police said she and Bush were known to frequent the Askern, Adwick, Woodlands and Highfield areas of north Doncaster. The force helicopter was scrambled on Wednesday to help with the search and police are trying to trace a silver Ford Mondeo in which Bush was seen. This year Bush was described as a "professional fraudster" by a judge who gave him a 14-month prison sentence, suspended for two years on condition that he did 200 hours of unpaid work. York crown court heard how Bush committed a range of frauds, including persuading garages to give him courtesy cars that he did not return and using a holiday cottage without paying.
