Mumbai: A team of the National Security Guards (NSG) from New Delhi arrived in Mumbai to examine the nature of explosive used in the bomb blast in a bus at Ghatkopar in northeast Mumbai on December 2, which claimed two lives and injured 31 others.

The team, which rushed to Ghatkopar, inspected the blast site to trace the kind of explosive used. The team would later visit SEEPZ at Andheri, where an explosive was found on December 2, police sources said.

The adjacent buildings at SEEPZ were evacuated early on December 3 even as the fire brigade personnel threw a cordon around the area.

Meanwhile, security has been stepped up all over the state with hundreds of police personnel being posted at sensitive zones in Mumbai.

Sniffer dogs were also pressed into service at various police stations and public places to detect presence of explosives, police sources said.

At various railway stations in Mumbai, regular announcements warning passengers of unclaimed bags were issued. The police also conducted random checks of luggage carried by passengers.
