Shop doors stop bungling serial robber William Carlin
A serial armed robber is facing another jail term after his latest offence was foiled when a supermarket door did not open fast enough during his getaway.
William Carlin, 49, was caught with a security box containing £40,000 at Sainsbury's in Prestwick, last October.
He pleaded guilty at the High Court in Glasgow and will be sentenced later.
Carlin has previous convictions for robbery in 1997, 2001 and 2007. The last one saw him foiled by a handbag-wielding 71-year-old grandmother.
The court heard that Carlin was carrying an axe when he held up security guard Robert Gilmour at the Sainsbury's in South Ayrshire.
'Face the devil'
He managed to grab a money box containing the cash before trying to escape but was caught when automatic doors to the store did not open quickly enough.
Carlin previously made the news in 2007 when a have-a-go grandmother tried to stop him carrying out a similar raid at a Kilmarnock supermarket.
Helen McAdam handbagged Carlin and told a jury at the time: "I'd face the devil. I've raised a big family and I am afraid of nobody."
Carlin was jailed for eight years following that robbery. He had been released early from that prison term when he committed this latest offence.
