Police are appealing for witnesses after a security guard delivering cash to a Lloyds TSB Bank in High Street, Ringwood, was robbed at around 9am this morning.
A man snatched the cash cassette he was carrying before riding off on a motorbike driven by another man.
They were last seen heading up Mansfield Road towards the duel carriageway.
The Black Honda SH300 scooter style motorbike was later found abandoned at Narrow Lane in Poulner, near the slip road on to the A31 eastbound.
The cash cassette was found empty nearby.
No one was injured in the incident but police said bank staff and the guard were "left shocked".
A search is currently being carried out and officers are appealing for witnesses to call Lyndhurst CID on 101 or Crimestoppers anonymously on 0800 555111.
