Gardai in Inishowen believe there may be a link between a robbery at a fashion store in Buncrana at quarter to four yesterday afternoon, and a similar incident in a chip shop in Muff on Monday night last.
In both instances, three people entered the premises, tied the hands of the woman behind the counter with cable ties and made off with an amount of cash.
