Extensive searches were carried out at the India Gate and police evacuated the area on Saturday after a telephone call about explosives being planted there, which turned out to be a hoax.
The police control room received the call at 10.55 am, following which visitors to the monument were evacuated from in and around the India Gate and bomb disposal squads accompanied by sniffer dogs and fire tenders were rushed to the scene, police officials said.
Searches were carried out for around 90 minutes and police declared the call a hoax at around 12.30 pm.
The call has been traced to a post office near Patiala House Court complex, the police officials said, adding investigations were on to trace the caller.
A series of hoax bomb threats, including one at Akshardham Temple, and an e-mail to Delhi Police threatening to carry out an attack at the Red Fort had kept the police on their toes who carried out searches at several places in the Capital.
