Detectives are investigating two aggravated burglaries at the homes of elderly householders in Co Antrim on Wednesday.
The first incident, which took place in Newtownabbey, was reported to police around 8.30pm.
Three men entered the home of a couple in their 70s at Bracken Drive through an unlocked back door.
One of the intruders held the couple in the living room while the other two rummaged through the upstairs room. It is not yet clear if anything was taken.
In the second incident, police believe thieves may have used a vehicle to force electric gates at a house on the Ballysavage Road in Ballyclare before entering the house around 10.25pm.
The occupant, a man in his 60s, was held down in bed by one intruder as the other searched the bedroom. The pair then made off with a safe.
The victims in both cases ere left badly shaken but otherwise uninjured.
A police spokesman said the incidents are not believed to be linked.
Detective Inspector Chris Millar said: “We are treating these incidents as two separate and distinct burglaries”.
He also appealed for anyone with information to ring the police non emergency 101 number.
