Police mop up Mahim rail tracks to collect clues

MUMBAI: To gather clues on the explosive device used in suburban trains on Tuesday, the police on Thursday collected a portion of a railway track at Mahim railway station near where one of the seven bomb blasts had occurred.

A pile of materials was collected from the spot by police and was handed over to the Anti-Terrorism Squad (ATS) which is probing the blasts that killed 200 persons and injured over 700, the sources said.

However, no substantial clues about the explosives have so far been found, they added.  Sources said some printed circuit boards (PCBs) were recovered from the spot but said it could be from any of the electronic gadgets which passengers travelling in the first class compartment may have been carrying.

Police officials dismissed reports that the circuit boards were those from the exploded bombs, saying no circuit would have withstood the impact of the high explosion.  Meanwhile, similar mopping up operations are likely to be carried out at other railway stations that had witnessed blasts on Tuesday evening, sources said.
