Cars stolen in Bradford, Leeds and Kirklees robberies
High-performance cars have been stolen in a spate of violent robberies, police say.
Robbers armed with knives, screwdrivers and pool cues have struck six times in two days at properties in Bradford, Leeds and Kirklees.
During one raid in Wyke, Bradford, a woman was attacked by four men before the gang made off with a Mercedes E250.
The robberies took place on Monday and Tuesday, West Yorkshire Police said.
The first robbery happened at about 18:40 GMT on Monday, when two men stole a VW Golf GTi from an address in Woodlands Crescent, in Gomersal, after threatening a man with a knife.
A Vauxhall Insignia was later stolen in Tyersal Park after a man was punched and threatened with a screwdriver.
A Mercedes A200 was then taken during a robbery in Bolton Drive, Bradford, at about 22:00.
'Similarities in raids'
The following day four men forced their way into a property in Lumb Bottom Drighlington and threatened the occupants before taking an Audi A4 estate car, police said.
About an hour later, an Audi Q7 was stolen by three men in balaclavas from a house in Langley Lane, Shipley. The vehicle was later recovered in Laisterdyke.
The final raid happened at about 21:00 when robbers targeted the property in Wyke.
Det Ch Insp Gary Hooks said there were a number of similarities between the raids and a team of specialist detectives had been appointed to investigate.
He said: "The level of violence used in these offences is clearly of concern and we are committed to keeping the public safe, so we would ask anyone who has any information about any of these offences to contact Bradford CID".
