CHENNAI: Another hoax bomb threat email was sent to the Greenways Road residence of former Chief Minister Edappadi K Palaniswami on Monday, the second in two weeks.

The threat was mailed to the city police control room, claiming that a bomb was planted at Palaniswami’s residence on Greenways Road and would explode shortly.

Personnel from the Bomb Detection and Disposal Squad (BDDS) were pressed into service, and after an extensive search, the threat was declared a hoax.

Police have alerted the cybercrime wing to trace the sender. On Monday, a hoax bomb threat was issued to the Madras High Court, too.

Ten days ago, hoax threat was sent to the US embassy and Anna University. In both the threat mails, the senders' names were the wife of a prominent politician and another party leader, police sources said.
