Police have appealed for information after a man in his 70s was tied up in his own home by up to three men during a aggravated burglary in Holywood.
Detectives believe two to three men entered the house in Downshire Road area of the town just before 10.45pm.
The householder was in bed at the time.
One man ran upstairs into the victim's bedroom and tied his wrists with cable ties. This man claimed he had a weapon and demanded money before dragging the older man down a flight of stairs.
The two struggled before a neighbour came to the house and raised the alarm just before 11pm.
The burglars then fled the scene.
Detective Sergeant Miskelly said: “The NIAS attended and treated the victim at the scene.
"Although not physically hurt in the incident, he was left very badly shaken. A mobile phone and a cordless landline phone were stolen from the house, which we believe may have been done to prevent the householder calling for help."
A 32-year-old man was arrested a short time later on suspicion of aggravated burglary.
On Saturday a 25-year-old man was arrested on suspicion of aggravated burglary with intent to steal.
Both men have been released on bail, pending further enquiries.
Anyone with information on the incident is asked to call 101, quoting reference number 1489 of 11/5/18.
