A 43-year-old man from Doncaster has pleaded guilty to four charges of fraud by false representation in which he obtained almost £30,000 from four women.
Jonathan Hill of Corona Drive, Thorne, appeared at Sheffield Crown Court for his Plea and Case Management Hearing and entered a guilty plea to all charges.
Hill was arrested in March last year following reports made to police by a woman claiming he had defrauded her of just over £18,000.
As part of the investigation, three further women were identified, who also claimed they had been defrauded by Hill for amounts of £10,963, £6,700, and £880.
Hill pleaded guilty to deceptively obtaining amounts totalling £28,785 between December, 2011 and August 2013.
Hill approached the women on internet dating sites, building up a relationship with them and gaining their trust to be able to defraud them by using bogus employment guises.
He claimed he was a debt collector to one of the women and needed money to assist his colleague who had been seriously injured on a job they were working on.
To the other three women, he claimed he was a covert prison officer and convinced them he needed money as he was unable to obtain any due to working undercover, or that he needed cash because his cover had been blown.
Hill will be sentenced at a later date.
DC Vicky Alcock investigating said: “I want to praise the women who have had the courage to come forward and report the offences; a deceptive crime is extremely difficult to face and overcome without blaming yourself.
“Hill is the only one to lay the blame on; he is a deceiving and calculated individual who knew exactly what he was doing.
“He was unemployed at the time and used the internet to search dating websites with the sole intention of finding females to exploit, manipulate and take advantage of financially and emotionally.
“I am pleased he has pleaded guilty and has saved his victims the ordeal of a trial. Hopefully they will now be able to put this behind them and move forward with their lives.”
