Since October, all 193 police stations in the city were keeping a tab on residential and commercial leasings in their respective jurisdiction after they received a circular saying: "Terrorists may sneak into residential buildings in the disguise of tenants and may cause explosion, riots, shootouts, affrays, etc."
The circular, undersigned by deputy commissioner of police (operations) KG Patil, was issued after the top brass reportedly started planning the execution of Pakistani Lashkar-e-Taiba operative Mohammad Ajmal Kasab.
The circular directed all senior inspectors of police stations to check the tenants’ documents and identification proof, and also mandated that the realty agents submit all required information to the police.
According to sources in the state government, soon after the home department rejected Kasab’s mercy petition that had been addressed to the President, the police reportedly discreetly started preparing firewalls to thwart any mischief by terrorist groups prior to the execution of the lone captured gunman during the November 26, 2008, attacks.
The home ministry did not want to face another Kandahar-like incident in which an Air India flight was hijacked to free terrorists.
