Craft beer giants Innis & Gunn have offered punters the chance of a free beer - if they have pinched one of their glasses. 

The hallmarked glasses are a regular target with over 70,000 pint glasses going missing from bars and pubs across Scotland since its conception in 2013. 

Innis & Gunn are offering customers a refill bag of lager by proving that they have once stolen a glass. 

Tomorrow customers will be able to pick up a bag by showing evidence of their glass at the brewer's Beer Kitchen on Edinburgh's Lothian Road.

The event will run between 5-7pm. 

Jane Cannon, Head of Marketing at Innis & Gunn commented:

"Our glasses our great, but what’s even better is the lager to go with it. Now our “borrowers” can enjoy the full Innis & Gunn experience at home.”

Innis & Gunn’s lager is the no.1 craft Lager in Scotland.
