Kolkata/IBNS: The Kolkata Police has intercepted one armed person near West Bengal Chief Minister Mamata Banerjee's residence in the city ahead of Trinamool Congress' Martyrs' Day rally.

The person, identified as Sheikh Noor Alam, was carrying a firearm, one knife and contraband substances besides having several ID cards of different agencies.

"He was traveling in a car with a police sticker on it. Police, STF and SB are examining and questioning him," Kolkata Police Commissioner Vineet Goyal said.

The rally, which is the annual mega political event of the ruling party, is held at Esplanade in downtown Kolkata.

On this day in 1993, 13 people were shot by police during the Left Front regime when then Congress youth leader Mamata Banerjee was leading a rally demanding that identity cards be made mandatory to cast votes.
