New Delhi/Bhopal: The Income Tax (I-T) Department on Sunday launched pre-dawn searches on at least 50 locations in Delhi and Madhya Pradesh against people linked to state Chief Minister Kamal Nath on charges of alleged tax evasion, officials said.

A team of about 200 I-T department officials and police officers swooped down on these premises around 3 am and some undisclosed cash was recovered, they said. The searches are linked to suspected movement of hawala money during the ongoing polls season and tax evasion, they said.
