Three men went to a house at Lurgan Road, Magheralin, Co Down, last night around 8.45 pm.
They demanded money and assaulted the man during the terrifying ordeal.
The gang then threw him into the car boot and drove off.
They abandoned the car near Moira and the victim was freed.
Police said it was a traumatic experience for the man who was left extremely shocked by what had happened.
They appealed to anyone who saw a blue Mazda and a silver Vauxhall car in Magheralin last night to contact them on the 101 number
