Acting Detective Inspector Simon Harrison said the cash in transit van was robbed in Birkenhead just before 2.30pm.
Security staff were carrying out a delivery to the ATM on Birkenhead Ave, he said, when a man approached them and stole a case of cash.
No one was injured and the man fled on foot, but it was believed he then left in a car.
The amount of money stolen has not yet been confirmed.
The brazen robbery shocked the community which is still reeling from a stabbing last week.
Police are asking those who saw anyone heading towards a vehicle carrying a case to contact them on 105, using the reference number P061584274.
Information could also be provided anonymously via Crime Stoppers on 0800 555 111.
