Detectives are investigating following an armed burglary in Brighouse last week.
The incident happened on Friday 7 December at around 10:25pm on Atlas Mill Road.
Suspects entered the property wearing balaclavas and some carrying weapons.
They made threats to the occupants and demanded money.
An amount of money was taken from the home and then fled on foot, onto Owler Ings Road, past The Bridge public house and down a canal towpath into Owler Ings car park.
From there it is thought they drove off in a white VW Golf, away from the town centre.
The suspects were described as male, wearing casual clothing and balaclavas.
Anyone who witnessed the incident or has any further information is asked to contact Calderdale CID via 101 quoting crime reference number 13180614134 or information can be passed to Crimestoppers anonymously on 0800 555 111.
