A brazen thief made away with $5000 in cash after a daylight bank hold-up on the Gold Coast today.

The robber was wearing a cap, sunglasses and a high-visibility work vest when he walked into a St George Bank branch at Runaway Bay Shopping Village and handed the teller a note demanding cash about 12.50pm.

The note said the man was armed, but he did not produce a weapon during the heist.

The man left with $5000 cash, which he stuffed in a shopping bag.

Police are searching for the thief.

Anyone with any information is asked to contact Crime Stoppers on 1800 333 000 or crimestoppers.com.au.
