Bengaluru, Dec 3 (IANS): About Rs 30 lakh unaccounted cash was seized on Saturday at two places in the city and three persons were arrested for holding it without documentary proof, police said.

"In one case, Ishwarappa, 66, a farmer from Andhra Pradesh, was nabbed at Whitefield for illegally carrying Rs 12.10 lakh in Rs.2,000 notes in a car to exchange them for old notes at 20 per cent commission," said a police statement.

In a similar case, two persons were arrested from near a private hospital at Hebbal for illegally carrying Rs 18 lakh in cash.

A patrolling police team nabbed Ishwarappa and his friend after a hot chase from a petrol retail outlet.

"On interception, the farmer confessed that he was asked to go tp the city by his contact to hand over the cash in return for old currency with commission. As he did not have documentary proof for carrying so much cash, we called the Income Tax officials and asked to ascertain the source of the amount," said the official.

In the other case, Sridhar and his friend Mohan, were caught waiting for their contact to deliver Rs 10 lakh in Rs 2,000 and new Rs 500 notes and Rs 8 lakh in Rs 100 notes.

"The duo was taken into custody and the cash was recovered from a car in which they were waiting to hand over to their contact. They were also handed over to the tax officials for investigation as they did not have documents to prove the money's source," added the official.
