National police spokesman Setyo Wasisto told AFP 75 people had been injured. "I saw many people bleeding," student Rizki Noviandi, who was taking part in a competition at the exchange building, told Metro TV. It was not immediately clear what caused the accident at the tower in Sudirman district, which was built in 1995. "Material degradation could be the cause," construction expert Iswandi Imran told local TV. The local office of the World Bank is housed on the 12th floor of the complex, according to its website.
