COIMBATORE: The District Collector’s office in Coimbatore received a hoax bomb threat mail warning of a blast coinciding with Prime Minister Narendra Modi’s visit on Wednesday.

A staff member who noticed the threat mail in the morning informed the Coimbatore city police. Soon, the Bomb Detection and Disposal Squad (BDDS) sleuths with a sniffer dog searched the entire premises, including the parking area and offices.

The threat was confirmed to be a hoax.

A similar bomb threat to the Tirupur District Collector's office also turned out to be a hoax after police made a thorough check in the entire campus.
