EIGHT men have been arrested in police swoops as the net closes around the gang behind a vicious armed raid at the Doncaster home of a wealthy businessman.
But police are still seeking the help of the public to provide further leads in the inquiry.
They particularly want to know more about the movements of two vehicles connected to the investigation - a black Audi A5 two-door coupe, and a Ford Transit van.
The Audi - distinctive because of its unusual wheels - was stolen in Rotherham a fortnight before being used in the armed robbery at the family home of Adrian and Vicki Welch in Spring Lane, Sprotbrough, on Friday, September 7.
A total of eight men have been arrested on suspicion of robbery as part of the investigation.
All are either from, or have strong links to, Doncaster.
The men are aged 18, 19, 22, 25, 27, 29, 31 and 43, and have been bailed pending further inquiries.
Police have also released a photo of the Audi A5 which is thought to have been involved in the daylight robbery, which took place as Mr and Mrs Welch’s two youngest children were playing in the garden at about 5.45pm.
The Audi is thought to have pulled into a field behind the property before two male occupants got out of the car, and entered the garden
The parents, who run a Doncaster glazing firm, and children were then threatened as the two men brandished knives and demanded money.
They left the house with a quantity of cash before making off towards Long Lane.
The Audi is believed to have left the scene at speed along Spring Lane.
A short time later, it is thought the two suspects were picked up by a white Ford Transit van.
Det Insp Richard Partridge said: “This was a very serious crime that targeted a family residence during daylight hours.
“The threats of violence in the presence of young children and the possession of weapons is a great cause for concern. We would like to encourage anyone with information about the vehicles to come forward to assist with our investigation.”
Officers want to speak to anyone who may have seen the white Ford Transit van in Sprotbrough at around 5.45pm on Friday, September 7.
And police believe the Audi A5, which has distinctive alloy wheels and was stolen from Rotherham on August 25, may have been used in the Barnsley and Doncaster areas.
