Gardai in Dublin are on the lookout for 36,000 pints of beer stolen from the Guinness brewery.
Kegs of Guinness were driven out of the brewery yard
More than 400 kegs were stolen in what is likely to be the largest carry-out of drink this Christmas.
A man drove a truck into the yard on Wednesday, and left with a trailer containing 180 Guinness kegs, 180 Budweiser kegs, and 90 Carslberg kegs.
Police estimated the haul to be worth at least 64,000 euros (£46,000), at wholesale prices.
However, this figure would be considerably more if Dublin pub prices were charged.
The robbery occurred the same day as a special Garda operation known as Freeflow was launched to ease traffic congestion and combat drink-driving over Christmas.
Freeflow officers manning many checkpoints across the city are expected now also to be on the look out for any large quantity of stolen drink flowing through Dublin's traffic.
The stolen trailer has since been found at Slane Hill in County Meath. It was empty.
