Police investigating the multi-million pound Securitas depot raid in Kent have found a quantity of money in a white Ford Transit van.
The van was recovered in Ashford after a tip-off to police
Detectives recovered the vehicle from the car park of the Ashford International Hotel on Friday.
Forensic officers wearing white overalls, gloves and face masks removed black bundles from the van.
Three people arrested in London over the robbery have been released on police bail pending further inquiries.
A 29-year-old man and a 31-year-old woman were detained at separate addresses in Forest Hill, south London, on Thursday.
Another 41-year-old woman was held in Bromley, south-east London.
Up to £50m was stolen by an armed gang who raided the Securitas premises in Vale Road, Tonbridge, during the early hours of Wednesday.
Earlier they had kidnapped the depot manager, 51-year-old Colin Dixon, and his wife and young son.
The armed gang forced the manager to let them into the depot
The Transit van was found in Ashford after a tip-off from a member of the public.
A police statement said money was recovered from the vehicle, but it was "too early to speculate on how much".
The van and its contents were taken away from the hotel and forensic examinations are now taking place.
Assistant Chief Constable Adrian Leppard said: "I am very grateful to the member of the public who made the call to us.
"I am as keen as you to know exactly how much cash [was in the van] but we just do not know at this stage."
The Bank of England said a £25m payment it received from Securitas on Wednesday had covered all its losses.
The rest of the stolen notes did not belong to the bank.
An audit of its own notes held at Tonbridge has now been completed but an audit of the rest of the cash is still under way.
Kent Police have now recovered several vehicles during the course of their investigations.
Mr Dixon's silver Nissan Almera was discovered at the Cock Horse pub in Detling.
A Volvo saloon which was believed to have been used in Mr Dixon's abduction, by robbers posing as police officers, was found burning in Burberry Lane in the village of Leeds, near Maidstone.
A red van with Parcelforce markings, thought to have been involved in the robbery, was recovered from the Hook and Hatchet pub in Hucking.
Police said they found another vehicle in Burberry Lane, although no more details about it have yet been revealed.
The white Renault lorry used by the gang is still missing.
Meanwhile, Kent Police have also released a description and computer image of one of the men who kidnapped Mr Dixon.
