Detectives are appealing for information following a report of an aggravated burglary in Dungiven on Monday, April 24.
Detective Sergeant Colhoun said: "It was reported just after 11.50pm that at around 11.30pm, two men knocked at the door of a property in the Dernaflaw Cottages area, before entering and stealing two firearms and a quantity of ammunition.
“One of the suspects forced a man upstairs to retrieve the firearms from a safe.
"All five people, which included a man, a woman and their three children who were in the house at the time, were thankfully physically uninjured, but have been left extremely shaken by the ordeal.
"One of the suspects is described as being around 6' tall, wearing dark clothing with a white snood, work boots and orange gloves. The second is described as being around 5' 5" in height, wearing a navy jacket, white snood and baseball cap with work boots. Both men had their faces completely covered, apart from the eyes and it is believed they left the area on foot.
"Our enquiries are ongoing and I would appeal to anyone who was in the area at the time and saw anything, or who may have dashcam, CCTV or other video footage, to contact us on 101, quoting reference 2035 of 24/4/23."
