Shop workers at the scene of a town centre jewellery heist tried to block the escape of a getaway car.
A helicopter and four police cars rushed to the scene of a robbery at Neimantas Jewellers on Commercial Street in Brighouse at 5pm this evening.
A witness at the scene said a woman ran into Boots with her two children, who were shaking after what they had seen.
He said staff from Wilko had tried to prevent the getaway car from leaving.
The raid is the third robbery on a jewellery shop in Calderdale within a week.
A spokesman for West Yorkshire Police said the incidents were not being linked.
No one is understood to have been injured in the Brighouse robbery and enquiries are ongoing.
