KUALA LUMPUR: Negligence is the likely cause behind the train collision in the tunnel between the KLCC and Kampung Baru LRT stations, says Transport Minister Datuk Seri Dr Wee Ka Siong. "We will investigate all possibilities and angles. We have our SOP, and those involved in the investigations are not those who are involved in the operations of the LRT because we have to be fair to all parties," he said. He also said that no stone would be left unturned in the investigations. “All our teams have started work, and we have identified the experts we want involved, ” he said.
