A Donegal garage and filling station owner was threatened with a knife on the forecourt of his premises earlier this week.
The incident occurred at the Clar Road in Donegal Town.
Two youths, one of whom had a knife, threatened the owner and made off after he handed over a sum of money.
In a follow-up investigation, Gardai arrested two people, who were held at Ballyshannon Garda Station.
Money was recovered and the pair were later released.
A file is to be sent to the Director of Public Prosecutions.
