A car window was smashed and an estimated £3,000 was stolen in a theft in Ipswich.
Officers are appealing for information to the incident, which took place at the Euro Retail Park in The Sandlings on Tuesday, October 24.
Between 10.10am and 10.30am, two suspects are believed to have watched a man withdraw £3,000 in cash from inside a bank.
The victim left the premises and got into his silver 4x4 pick up truck, before driving to the nearby B&Q.
When he was inside the B&Q, the suspects smashed a passenger window to break into the vehicle and took the money from inside.
A spokesman for Suffolk Constabulary said: "Police are asking for people to stay vigilant if they are withdrawing large amounts of money from banks and would advise them not to leave any cash amount or valuable items in their vehicles and to report any suspicious behaviour."
Anyone with information is asked to contact Suffolk police quoting crime number 37/62205/23.
