The man, identified as Shibesh Adhikari, turned out to be a martial arts teacher from Fatehpur Sikri in UP, said DCP (Metro) Jitender Mani, adding that Adikari is now suspected to be a mentally deranged person.
"During questioning, Adhikari claimed that on September 28 he received information about a man who had plans to blow up Delhi Metro on Thursday evening," said a senior police officer.
When the cops grilled him hard on how he had managed to sneak inside the metro station premises at Chandni Chowk (in Yellow Line of Delhi Metro) with the gun, he told them that he had no weapon with him when he was frisked at the security gate.
"He had instructed his sister to wait near the glass pane - which is around three feet high - between a customer care cabin and one of the Automated Fare Collection (AFC) gates meant only for exit and had asked her to hand over a bag once he was inside after being frisked by security personnel," said the officer.
