Detectives have issued these CCTV images of suspects they are seeking in connection with a brutal robbery at a family home near Keighley.

Hooded raiders tied up a father and his two sons in the terrifying early-morning incident on February 29.

The robbers woke the family at their large house in Bronte Villas, Cross Roads, bound the hands and ankles of the 53-year-old home owner and his adult sons and ransacked the house, before making off with a “substantial” amount of money and valuables.

Detectives said the family had suffered a "terrifying ordeal”.

The raiders broke in through the conservatory. They dumped some of the stolen property in Haworth Road, Harecroft, near Cullingworth.

Police hope the new images will help trace the robbers.

Detective Inspector Richard Partis, of Airedale and North Bradford CID, said: “Although the images captured on the CCTV are not of sufficient quality to clearly identify the individuals, they may well jog someone’s memory.

“Despite this being in the early hours of the morning, there may well have been passers-by who remember seeing three men dressed in dark clothing.

“Just recalling even the smallest piece of information could trigger further investigation and potentially lead to an arrest.

“I would ask anyone who knows they were in the area at the time to think back and let us know if you can help us further in this investigation.

“This was clearly an extremely upsetting and scary experience for the occupants of the property and it is important that we quickly trace those responsible.

“If you believe you have witnessed this or have any information which could assist our inquiry please call Airedale and North Bradford CID on the non-emergency number 101 or Crimestoppers in confidence on 0800 555 111.”

The victims were left badly shocked but otherwise uninjured.
