New Delhi: The Intelligence Bureau has found a letter written by arrested Jammu and Kashmir Police Deputy Superintendent of Police Davinder Singh in 2005. The letter asked for "safe passage" to one of the four terrorists arrested by Delhi Police on the Delhi-Gurugram border on their way from Kashmir to Delhi. This comes in the wake of reports that Singh had helped other terrorists as well even as it has been revealed that Parliament attack convict Afzal Guru had mentioned his name in a letter to his advocate.

The National Investigation Agency (NIA) will now also probe Singh's 2005 letter, sources said. IB sources said the Delhi Police had arrested four terrorists after a gunfight from the Gurugram-Delhi border on July 1, 2005 and recovered arms and ammunition besides fake currency of Rs 50,000 from their possession following a tip-off received from the Military Intelligence on June 22, 2005.
