A 41-year-old man has been arrested in connection with a robbery in Limavady.
Detectives had appealed for information following the incident at a supermarket in the Main Street area of the town on Saturday night.
At around 9.30pm the manager of the store was making his way to work along the Barnault Road in his blue Volkswagen Bora when he was stopped by four men in a black BMW.
They threatened him and ordered him to open the safe in the supermarket.
He was then directed to drive to the Buncrana area of Donegal where a substantial sum of money was handed over to the thieves.
The manager was unhurt but badly shaken by his ordeal.
