The Election Commission officers in Tamil Nadu on 14 May seized about Rs 570 crore from three containers in Tiruppur district - ahead of the 16 May assembly polls in the state.
The men in cars, who claimed to be policemen from Andhra Pradesh, told the officials they were transferring Rs 570 crore from State Bank of India in Coimbatore to Vishakhapatnam branches.
However, they could not produce any proper documents to substantiate their claims, following which the vehicles were taken to the District Collectorate in Tirupur.
The flying squad of the election department, along with paramilitary forces, seized the cash early on 13 May during a routine vehicle check on Perumanallur-Kunnathur Bypas, police said.
The containers, which were escorted by three cars, did not halt. But the officials chased them and stopped them near Chengapalli.
