The Union Home Ministry has served a showcause notice to just-retired Chief Secretary of West Bengal Alapan Bandyopadhyay under the Disaster Management Act, officials said.

A home ministry official said the notice was served on Bandyopadhyay hours before his retirement on Monday for refusing to comply with the Central government direction, which he said constituted a violation of section 51-B of the Disaster Management Act, 2005.
