A police team escorting arrested NCP leader Ramesh Kadam to Thane Central Jail after a medical check-up stopped at a flat on the latter's insistence on Friday evening and stumbled upon Rs 50 lakh cash, an official said.

Kadam, NCP MLA from Mohol in Solapur, was arrested in August, 2015 for alleged irregularities to the tune of Rs 150 crore in state-run Annabhau Sathe Development Corporation (ASDC) when he was its chairman.

The police escort team took Kadam to the flat and found Rs 50 lakh cash, he added.

"The antecedents of the cash as well as why the escort party took a detour on Kadam's insistence are being probed. Poll officials and senior police personnel have reached the flat," he said.
