New Delhi, Sep 11 - Delhi Police received yet another hoax call Friday warning of a bomb blast in Connaught Place, the heart of the national capital, officials said.

'The call came on a landline of a computer institute whose office is in Connaught Plale at around 9.30 a.m. It threatened that a bomb had been placed in the inner circle of Connaught Place,' a senior police officer said.

'They informed us and immediately police personnel, bomb disposal squads and dog squads were pressed into service. The call was declared a hoax after two hours of extensive research,' the police officer added.
