Police are appealing for witnesses after a stolen car was spotted in a Wyre village following a foiled raid on a cash delivery van.
The original incident happened on Friday at around 10.30am when two vehicles were spotted following a Mercedes delivery van through Lancaster city centre.
Both of the cars were quickly intercepted but then drove off at speed through the city.
One of them, a stolen silver Audi TT with the registration number MT12EWH, mounted the pavement on George Street, hitting a police officer who was attempting to stop it.
He suffering minor bruising.
The second car, a stolen white Audi A6 estate, registration DU61TXY, drove off down Aldcliffe Road and was last seen on St Michaels Lane in St Michaels village around an hour later.
The police are appealing for witnesses that may have seen both Audis.
Det Insp Phil Jones said: “I have no doubt that the Greet Team security guard’s diligence and the swift response by the police officers foiled what would have been an attempt to rob the guards of a substantial amount of money.”
