Bank SA employee Anna Martha Hein denies she was part of Mannum heist Accused bank robber Anna Hein leaves the District Court. Source: adelaidenow A BANK employee has denied being the "inside woman" for an armed hold-up, insisting she was frozen in fear during the robbery. Anna Martha Hein, 37, of Murray Bridge, took the stand in the District Court today. She has pleaded not guilty to one count of aggravated robbery. Opening the trial, Deputy Director of Public Prosecutions Sandi McDonald said the charge arose from an incident in December 2009. "The Bank SA branch at Mannum was robbed," she said. As staff were getting ready to open, a man forced his way in, bound and gagged one of the staff and left her in a toilet cubicle. Anna Hein, who is facing a robbery charge, leaves the District Court. Picture: Greg Higgs The other staff member was Anna Hein, and he kept (her) with him to gain access to various large sums of money... he fled with roughly $120,000. Ms McDonald told jurors the robbery was not as opportunistic as it appeared. "Hein was involved in arranging and facilitating this robbery - she was the person on the inside," she said. She helped her friend, the robber Justin Lundberg, rob the bank at which she worked. Ms McDonald said phone records showed Hein and Lundberg had communicated more than 800 times in the months leading up to the robbery. They spoke 70 times in the week before the incident. She said Lundberg was a former Bank SA employee who had "not left on particularly good terms." "He owed $30,000 (to bikies) and that debt was well and truly overdue for payment," she said. Hein's role was subtle... by providing information, she enabled the planning and execution of this crime. Giving evidence today, Hein rejected those allegations. "As I started to walk into the bank, someone pushed past me," she said. That person said 'this is not your lucky day' and pushed me inside the bank fully. (My co-worker) got taken into the bathroom... I was frozen with fear. Hein said she used her employee's code to open the bank's safe to comply with the robber's demands. "I was scared," she said. The trial, before Judge Gordon Barrett, continues.
