THREE branches of the Standard Chartered Bank in Wan Chai and North Point were robbed of a total of $113,000 within three hours yesterday. The first raid was at 1.30 pm when a man with a pistol entered a branch at 1 Hennessy Road. A teller gave him $3,000 and the robber fled. An hour later, a man with a pistol grabbed $50,000 from a teller at the bank's North Point office at 284 King's Road. Then just before 4.30 pm, a man walked into the 3 Fleming Road branch in Wan Chai and escaped after demanding $60,000.
