A family have offered a £50,000 reward to help catch armed robbers who tied them up in their home.
Four masked men forced a window of the house open on the outskirts of Skipton, North Yorkshire, at 2300 BST on 31 July.
The middle-aged couple and their teenage daughter were threatened with a shotgun and tied up.
They were then forced to reveal the combination for the safe and put in a cellar while cash and jewellery were stolen.
'Interesting leads'
Police investigating the robbery say they have found a shotgun in the grounds.
It has been sent away for forensic examination together with other items recovered from the property.
Detective Inspector Mick Moore said: "We have only had a limited response to appeals for information which was to be expected given the location of the house concerned.
"But the information we have received has thrown up some interesting leads and these are now being followed up."
Police say the £50,000 reward is being offered for information which leads to the conviction of those responsible.
