31 year old victim taken to hospital after attack on Thursday night.
Hunt For Murder Weapon
Police investigating the killing of a 76 year old Hungarian man are asking the public to look out for the murder weapon.
Officers in Northamptonshire have been looking for some kind of blade since Karoly Varga was found dead at home in Wellingborough on Saturday 30 July 2011. It's thought he was killed the day before.
A search of the outside of Karoly Varga's terraced house in Cannon Street was finished on Tuesday 2 August, but police have been unable to find the murder weapon.
The inside of the 76-year-old's home is still being forensically examined before a physical search can take place. It is expected that officers will remain at the property for at least two more days.
Hungarian-born Mr Varga - who was known as Charlie - had lived in the UK for 30 years. Police were called out on Saturday after a concerned relative was unable to make contact with him.
The father-of-three adult children had suffered a head wound caused by a bladed weapon.
An S-registered Peugeot 306 which was for sale, privately, outside Mr Varga's home has been traced. Officers are in the process of establishing whether it can be eliminated from their inquiries.
Local people are being spoken to and Northants police are distributing leaflets written in Hungarian appealing for information.
Detective Chief Inspector Martin Kinchin, leading the investigation, said: "We are currently following a number of leads in the investigation. We received very good feedback following the public appeal for the car. Within a matter of hours following the media coverage a member of the public came forward identifying the vehicle.
"I want to continue appealing to members of the public, friends or family of Mr Varga to come forward with any information they may have.
"We know that Mr Varga frequently shopped at Lidl and often walked or cycled to most places. It is entirely likely that someone may have seen him on Friday.
"It is also likely that someone may have seen a person or people leaving the property with blood on their clothing.
"We would urge anyone who knows or saw anything on Friday 29 July to come forward."
Anyone with information can call Northamptonshire Police on 03000 111 222 or call Crimestoppers anonymously on 0800 555 111 .
Both robberies happened within 20 minutes of each other on Wednesday night.
