NEWDELHI: Home Minister P Chidambaram on Tuesday said that the apparent rift between Maharashtra Anti-Terrorism Squad (ATS) and Delhi Police over the arrest of a person in connection with the 13/7 Mumbai blasts underlined the need for a better exchange of information between the two forces. The two police forces have been involved in a verbal slugfest over the arrest of Naqi Ahmed by the Maharashtra ATS in connection with the three serial blasts. The Delhi Police have claimed that Ahmed was its informer. “These are difficult cases and yes I would have liked better exchange between Delhi Police and Maharashtra ATS, but as you know there are two different police and two different state governments and therefore, there may have been inadequate exchange of information,” he said. Chidambaram said that the problem could be resolved once the National Counter Terrorism Centre is set up. ;ENS
