Two suspected Jaish-e-Mohammad (JeM) militants were arrested by the Delhi police at the Old Delhi railway station on Monday. A hunt is on for their contacts here. The arrests followed a tip-off that the two were aboard the Kalka-Delhi Mail. Police seized two kg of RDX and Rs. 5 lakh in cash from them. During interrogation, the duo purportedly disclosed that they were JeM militants. "We are trying to find out whether they had been given any target," said a senior police officer. Last week, two alleged conduits of the banned terrorist outfit Lashkar-e-Taiba were arrested.
