Detectives are hunting a gang of masked men armed with a handgun and a cosh burst into a Halifax home.
The three men forced their way into the house on Mount Pleasant Avenue, off Pellon Lane, in Halifax at around 5pm yesterday.
They demanded money from the people inside before leaving with a number of mobile phones.
The suspects, who were all wearing gloves, hooded tops and face-coverings, made off towards Dean Clough on foot.
Police say inquiries are ongoing to establish the circumstances behind the incident and CCTV is being studied.
Any witnesses or anyone with any information is asked to contact Calderdale CID on 101 or Crimestoppers on 0800 555 111.
