Income Tax department officials are conducting searches at 10 locations in Bengaluru, Chennai and Delhi as a follow up to raids at various properties linked to Karnataka Minister DK Shivakumar earlier this month. In a swoop down that had stirred a political controversy, the I-T department had in the first week of August raided various properties linked to Mr Shivakumar, who hosted 44 Gujarat Congress MLAs at a resort on the outskirts of Bengaluru, to thwart "poaching" attempts by the BJP ahead of the Rajya Sabha election in Gujarat.
