Bokaro (Jharkhand), March 9 Panic spread in the civil court of Bokaro district in Jharkhand on Monday after an email threatening to detonate over a dozen bombs was received on the official email address of the registrar, police said.
SP Harvinder Singh said the email claimed that 14 "cyanide bombs" had been planted in the court premises and threatened to blow it up if it were not evacuated by 1 pm.
The message allegedly mentioned Pakistan's intelligence agency, ISI, and Tamil Nadu.
Police evacuated the court premises and cordoned off the adjacent areas to restrict people's movement.
"Given the seriousness of the case, immediate action was taken, and a large-scale search operation was launched by local security personnel, with the Jaguar squad called in from Ranchi," Singh said.
Preliminary investigation has not revealed any concrete links, but technical examination of the email is underway to identify its origin, he added.
The Ranchi ATS has been informed about the incident.
"At present, no suspicious object has been found, but the operation is still ongoing," Singh said.
