New Delhi (PTI): An email threatening to cause bomb blasts in the national capital was on Wednesday received by the Japanese Embassy, which alerted the Delhi Police.

As a result of the e-mail threat, the Japanese Embassy and its cultural centre has been closed temporarily.

The embassy received the mail in which it was stated that after the blasts in Jaipur and Ahmedabad, there will be bomb blasts in Delhi, sources said.

In the mail, Sarojini Nagar area was identified as one of the targets. Sarojini Nagar market was targeted by terrorists in October 2005.

The email was immediately passed on to Delhi Police for further investigations.

Security has been stepped up at the embassy, sources said adding that the capital is already on a high alert following the serial blasts in Bangalore and Ahmedabad last week.

A senior police official said they were investigating the origin of the email.
