A Poppy Appeal money box was stolen from a fast food outlet on Remembrance Day.
The collection for The Royal British Legion to support former and current service men and women was taken just after midnight on Sunday morning from Favorite Chicken & Ribs in Stevenage High Street.
Proprietor Peter Cook said it was a “sick” act.
The collection box, which Mr Cook said was full of change, was later found empty in a bin in nearby Middle Row.
It is the second time the takeaway has been targeted, after a Poppy Appeal box was stolen last year.
Police want to speak to a man captured on the shop CCTV in relation to the theft.
If you recognise the man in the parka jacket and blue jumper in the footage, call Herts Police on 101 with crime reference number E1/12/6882.
