This is the chilling moment a knifeman was caught on camera after breaking into a family's home in the middle of the night.
The masked intruder, clad in a balaclava, wandered around the living room carrying a knife while one family member was asleep on an armchair.
The man broke into the house in Chadderton, Greater Manchester, but it is not believed he took anything.
He was filmed by a device the family use to monitor their pets while they are out of the house.
At one point in the clip, the intruder looks over Jason Skilling, 53, who was asleep at the time on an armchair in the living room.
His wife, Adelle, 56, was asleep upstairs at the time.
The knifeman looks at the camera at one stage and adjusts his balaclava.
Adelle's daughter, Ashleigh Jones, 33, said: "My mum had checked the cameras that they have in the house to watch their pets while they are out.
"She had seen a guy walking around the front room with a massive knife, whilst my stepdad was asleep on the chair.
"It is really scary, my mum is really upset by it. She keeps thinking, what if we did wake up."
Ms Jones said the family have "upped their security" at their home after the incident.
"They are checking the cameras all the time and making sure everything is working," she said.
"When they lock up at night, my mum is making sure that everything is locked up when she goes to bed.
"My six-year-old son is terrified, he keeps mentioning it. My first thought when I saw the video was, what if Jason would have woken up.
"My mum doesn't sleep very well, so sometimes she goes downstairs at 3am and has a cup of tea.
"It's all so worrying knowing that that person was there. It is wild when you think that somebody has been in a house like that, so close to you.
"I'm sharing what has happened because it's hot, and I know so many people who leave their windows open, stay up late at night and then fall asleep on the sofa.
"It is so dangerous now, you are not safe in your own home."
Greater Manchester Police told Yahoo News UK they are investigating two attempted aggravated burglaries in the area.
In a statement, the force said: "We have received reports of attempted aggravated burglaries on Stirling Road, Chadderton.
"Initial enquiries suggest that a man has gained access to properties and has been walking throughout the houses in the area, using a knife to promote fear."
Detective Sergeant Matthew Adshead said: “Thankfully, no one has been injured, but it is understandable that people in the community are worried for the security of their homes.
“Our investigation into this incident is ongoing and officers are appealing for anyone with information or CCTV footage that could help us with our inquiries.”
