Several museums, including the National Museum and Rail Museum, and two mental health institutes -- IHBAS (Institute of Human Behaviour and Allied Sciences) and VIMHANS (Vidyasagar Institute of Mental Health, Neuro and Allied Sciences) -- have received bomb threat e-mails, officials said on Wednesday.
The officials said that nothing suspicious was found in the searches and later the calls were declared hoax.
The e-mails were received by the National Museum in Kartavya Path, Rail Museum in Chanakyapuri and Gandhi Museum in Daryaganj and several others stating that the bomb was planted in their premises, they said.
Two medical facilities -- IHBAS located in Shahdara and Vimhans Hospital in Lajpat Nagar -- have also received the threat e-mails containing the same contents, the officials said.
An officer said that after receiving the calls and information about these e-mails, the installations were checked by the bomb detection team, bomb disposal squad, fire officials and local police but nothing suspicious was recovered from any of the places.
Over the past one month, bomb threat emails have been received by many establishments, including schools and hospitals in the national capital.
