A THIEF crept into the cab of a unlocked lorry and grabbed a mobile phone which its owner had left sitting on the front seat, a court heard.
Derek Jervis (32) was later identified as the culprit but the phone was not recovered.
A court heard that Jervis has battled a problem with heroin for nearly half his life, and he was stealing to feed his habit.
Judge David McHugh sentenced Jervis to six months in prison.
The defendant, with an address at Crannoge Road in Ballymun, admitted before Blanchardstown District Court to stealing a Samsung Galaxy mobile phone, worth €500.
The incident took place at Glasnevin Avenue in Ballymun on April 8 last.
Garda Sergeant Mary Doherty said that Jervis snatched the mobile phone from the cab of an unlocked 2004-registered lorry. The phone was not recovered.
The court heard that the defendant has 67 previous convictions, including 17 for theft-related matters.
Defence solicitor John O'Doherty said Jervis has had a heroin problem since he was 17 years old and he has been in and out of Coolmine Treatment Centre.
In relation to this incident, Mr O'Doherty said Jervis was stealing to feed his habit.
Mr O'Doherty said the defendant is currently stabilised on methadone, and is focused on staying off drugs.
The solicitor accepted the mobile phone was not recovered and the owner was at a loss of €500, but said there was no reality to Jervis paying compensation.
Mr O'Doherty said Jervis, an unemployed father of two, enjoys the support of his mother, who has loyally stood by him through all his problems.
Judge McHugh said the defendant's mother was "very loyal and long suffering".
The judge said the mobile phone was not recovered and he imposed a six month sentence. He refused to suspend any part of the six months.
