A serial robber was caught after a shop assistant disarmed him and sat on him until gardaí arrived.
Michael O'Connor (27), tried to rob the Glencar filling station in Letterkenny, Co Donegal with a six-inch knife on March 30th last year.
He shouted at shop assistant James Doherty to give him the money and threatened him with a knife.
However, Mr Doherty managed to overpower him and lay on top of him until gardaí came.
Once arrested, O’Connor, who was wearing socks over his shoes to avoid his footprints being detected, then admitted to robbing another shop on Letterkenny’s Main Street.
Letterkenny Circuit Court was told that the previous week, on March 24th 2013, O’Connor entered Callaghan’s XL store wearing a balaclava and waving a six-inch knife.
He demanded the money from the cash register from shop assistant Aidan McLaughlin, who put €759 into a bag.
O’Connor fled down a side lane and was later stopped by gardaí, but the cash was never recovered.
The court heard O’Connor, who is originally from Kildare, had 43 previous convictions, many for robbery.
O’Connor’s barrister said his client had grown up in a very challenging environment after his mother died and father left the family home at a very young age.
He had been put into foster care but had since become a heroin addict.
He is currently in Portlaoise Prison serving another sentence, but is now drug-free, working in the prison and doing well.
Judge Keenan Johnson said robberies by heroin addicts with violence are all too common and they the courts must "deal with them in a firm way".
“He has a deplorable record which shows he has been involved in numerous robberies,” said Judge Johnson.
But he added he appeared to be trying to become an upstanding member of society.
He sentenced O’Connor to four years in prison for the first robbery and five years in prison for the second robbery, but suspended this for five years.
