Bank of China (BOC) officials are investigating the alleged theft of 2.6 million yuan in cash by a branch manager from the vault of his own bank. Xiao Kui, operations manager at BOC's Yicheng city sub-branch in Hubei, allegedly walked out of his bank with the cash stuffed in a large bag on November 26, according to mainland media reports. The theft was not uncovered until a week later. The manager had previously applied for annual leave and the robbery was not discovered until Sunday night, when he failed to show up at work to open the safe in preparation for business on Monday. When employees finally managed to open the safe they realised the money was missing. In two separate cases reported yesterday, a land administration official in Zhengzhou , Henan province , and a BOC official on Hainan Island were each sentenced to five years in prison for accepting bribes. Dong Jili was sentenced for taking 'massive bribes' from a real estate developer in Zhengzhou in return for approving land sales, and Tang Xiaoping was convicted of taking a 100,000 yuan bribe in return for approving a loan to a real estate company, according to Xinhua.
