A man prevented a robber stealing his car in Salford by throwing a brick through the window.
Just after 6am on Saturday 2 April 2011, the householders on Gerald Road, Charlestown heard loud bangs at the front door.
A 41-year-old man walked downstairs to investigate the noise, when he was confronted by a man wearing a balaclava.
A struggle took place before the victim was pushed onto the stairs and the offender stole the keys to his Seat Leon.
He got into the car and drove off, with the victim giving chase.
In an attempt to stop the vehicle, a brick was thrown through the driver's window.
The man got out of the car, threatened the victim with a knife before running off in the direction of Norfolk Street.
The offender is described as:
- a white male
- 5ft 9in tall
- slim build
- wearing a balaclava and black tracksuit
- spoke with a local accent
It is believed the offender may have an injury to his right shoulder as a result of the glass being smashed.
Police Constable Adele Ainscough from the Volume Crime Team said:
"I would urge anyone who may have seen something suspicious to contact us as soon as possible.
"We believe there was a taxi travelling along Gerald Road moments after the incident and I am appealing for the driver to come forward.
"We also believe two people were walking along Cromwell Road at this time and would like to talk to them so we can eliminate them from our inquiries."
