False claims were made to an insurance company after a 21-year-old man was unable to get his mobile phone back from his ex-girlfriend.
Ryan Rowarth, of Edward Street, Grantham, admitted fraud by false representation after falsely claiming to the company which insured his Samsung Galaxy 3 that he had lost his phone while at Skegness market.
The offence came to light when the phone was sold online, along with the original box and documentation.
The buyer found the phone was locked out and could not be used as the insurance company had shut it down.
Paul Wood, prosecuting, said: “He was arrested by police and initially stuck with his story but his story did not make any sense.
“He now pleads guilty.”
Rory Macmillan, defending, said the phone was sold “unbeknownst to him” but admitted the offence as he knowingly gave false information to the insurance company.
Mr Macmillan said: “It’s a badly thought through series of events.”
Rowarth was fined £65.
He was also ordered to pay £85 costs and a surcharge of £15.
