Two men forced open the doors of a betting shop and smashed glass to access the till area.
At around 10pm on May 24, a member of staff was closing the Ladbrokes store in Manor Way, Borehamwood.
Two men approached the store and forced their way in.
One remained at the front of the property while the other smashed the glass to access the till area.
A search was carried out before they both made off. Nothing was taken.
Detective Constable Rob Fleming is asking to speak to the two men pictured in the CCTV released by the police.
Anyone who recognises the men should contact Hertfordshire Constabulary on 101.
