Gardaí in Donegal are continuing to question a man in his 20s in connection with a robbery at a businessman's home in Buncrana yesterday.
A gang of up to four men broke into the house, threatened the man's wife and children at gunpoint and stole a substantial sum of cash.
The thieves made their getaway in the victim's car, a Blue Audi A6. The car was later retrieved by police in Derry.
Gardaí are appealing for anyone with information to contact them at 074 93 20 540.
