A woman suffered three breaks to her arm when she was viciously attacked with a gardening tool in her own home.
The victim, 67, and her 65-year-old husband, were robbed at their home on Pennine Close in Blackley at about 11.30pm on Friday 22 January 2010.
The couple were about to go to bed for the night when the victim answered a knock on the door.
She was confronted by three men, who burst into the house and demanded the keys to the couple's car - a Jaguar parked out front.
One of the men was brandishing what appeared to be a lawn edging tool and the couple struggled with the armed robber trying to protect themselves.
The victim suffered three breaks to her arms and cuts to her face, and her husband sustained a suspected fractured wrist.
The gang managed to steal the keys and the car.
Amongst other items stolen are:
- a computer
- a satellite navigation system
- a watch
- a CD player
- a quantity of cash
The car was later found on Birkdale Street in Cheetham Hill.
The three offenders are described as:
- white males
- about 6ft tall
- wearing dark clothing, face masks and spoke with local accents
Police are now appealing to anyone who has information to come forward.
Detective Inspector Mark Hudson, of Grey Mare Lane CID, said:
"I'm sure anyone reading this will rightly be appalled at the actions of these cowardly men, who have attacked an innocent couple in the sanctity of their own home with what appears to be a gardening tool.
"This tool is sharp edged and looks like a small crescent shaped spade, which could potentially have inflicted serious injury.
"The woman has suffered three breaks to her arm as well as the emotional trauma of having her home invaded, so the best remedy is to catch these men and lock them away.
"The public can help us find these men by reporting any suspicious activity they saw around this house at about the time of the robbery.
"You might have seen the men going in or the Jaguar being driven away at speed.
"Any little piece of information could be vital to us so please do come forward.
"Greater Manchester Police has put a lot of violent robbers behind bars, and with the public's assistance we will do all we can to find these three men and send them to prison where they can cause no more distress."
Anyone with information is asked to call Grey Mare Lane CID on 0161 856 3540.
