Serial burglar David Castell was jailed after carrying out a double raid on the changing rooms of a Preston school.
The 37-year-old was captured on camera as he stole a mobile phone from a locker at the swimming pool of Hutton Grammar - and later confessed to another theft from the same premises seven weeks earlier.
Castell, who had 35 previous convictions involving 56 offences, was sent to prison for eight months at the city’s crown court.
Recorder Simon Berkson told him: “You have a terrible record - and a terrible record for burglary. These offences were committed whilst you were on licence from a lengthy sentence for burglary.”
The court heard Castell, of Hampstead Road, Ribbleton walked into the ladies’ changing area at Hutton and took an i-Phone worth £600 from a locker. He was disturbed by the phone’s owner and after a confrontation he fled.
CCTV pictures showed him entering the grounds of the school and then the changing room area. He was recognised and arrested two weeks later.
When police interviewed him he confessed he had carried out another burglary at the school, also involving a mobile phone.
Daniel Prowse, defending, said the offences had been committed to fund Castell’s addiction to drugs. Whilst he had been in custody he had transferred to a drug recovery unit.
“This is the first time he has sought to go cold turkey,” he added. “He has been making good use of his time in custody and he is hoping this will be the end of his offending.”
Recorder Berkson said: “This was a nasty offence.”
