The main accused, Vijay Debnath, an employee of a private company engaged to deposit cash in the kiosk, was first picked up and from his rented house and the stolen money was recovered, the officer said.
"We have arrested four persons involved in the criminal conspiracy to loot the kiosk. Interrogation is on," Superintendent of Police, West Garo Hills, R Kumar said.
Debnath was responsible for filling the cash at the vaults of the SBI ATM machines. He was arrested by police along with three others for their alleged role in the ATM heist that took place on Tuesday night, the SP said.
Police suspected the handiwork of some insider in the ATM heist and sought the CCTV footage of the ATMs which confirmed the involvement of the accused.
The four accused had taken Rs 39,86,400 from the ATM and in their hurry, abandoned Rs 1.5 lakh in the machine.
Their modus operandi is to obtain the password from another employee to crack the ATM vaults to steal the cash, the police added.
