A man and woman were threatened with machetes in East Didsbury after thieves entered their property on Kingsway on Sunday evening.
Three men broke into the house through the front door, armed with machetes and a baseball bat, and threatened a man and a woman in their 60s, before stealing money and jewellery.
One of the offenders held a machete to the man’s throat, punched him several times in the head, and threatened to kill him if he didn’t hand over valuables.
The woman was forced upstairs by one of the offenders who then held a machete to her throat, punched her in the face, and threatened to kill her if she didn’t comply.
The offenders then fled the scene with a quantity of cash and jewellery in a black 4×4 vehicle.
Detective Inspector Madeline Kelly, from GMP’s City of Manchester Division, said: “These criminals have put their victims through a truly harrowing ordeal. No one should be subjected to such a terrifying attack in their own home.
“Enquiries are ongoing to establish the full circumstances of what happened, and I am appealing for anyone with any information about this incident to please get in touch with the police as soon as possible.
“Perhaps you were driving along Kingsway and saw something, which now on reflection may be relevant. My team are on hand to follow up any lines of enquiry.
“We are determined to find those responsible for this terrible crime and ensure that criminals like this are off our streets.”
Anyone with information should call the Police on 101 quoting incident number 2075 of 12/08/2018, or the independent charity Crimestoppers, anonymously, on 0800 555 111
