MUMBAI, Dec. 19 -- The Bombay High Court and three magistrate courts in the city were evacuated on Thursday after authorities received emails claiming that powerful bombs had been planted in the premises. The police and the bomb squad conducted a thorough search and declared the threats a hoax. According to the police, the high court in Fort and the magistrate courts at Esplanade, Andheri and Bandra received threat mails on Thursday morning, following which teams from the Mumbai Police and the Bomb Detection and Disposal Squad rushed to the locations, evacuated the buildings and conducted extensive searches. The threat email claimed it was part of a "Pakistan ISI-DMK Plan" and alleged that RDX-laden improvised explosive devices had been planted in the courts, specifically targeting judges' chambers. "4 RDX IEDs to blast soon in your court, specifically Judge Chambers. Evacuate all by 2 pm," the email stated. After thorough inspection of the courts' premises, the police declared all the threat mails as a hoax. "Proceedings at the Bombay High Court were suspended until 3 pm after the entire court complex was evacuated around 1.15 pm," said a police officer....
