A witness appeal on BBC's Crimewatch has prompted more than 100 calls to Herts police.
The show featured a reconstruction of a robbery at an ATM machine as it was being refilled in Wheathampstead earlier this year, where a gang of masked men threatened staff and robbed the machine.
Police confirmed they were following up a number of promising leads as a result of last Thurday's broadcast.
