The unidentified robbers used a gas cutter to remove the front portion of the machine to decamp the entire cash from the ATM in the wee hours near Pratapnagar, DCP Kunwar Rashtradeep said.
Bank's online monitoring system made a call of theft to the police after two hours around 03:15 hrs, DCP said.
Police have alerted the toll plazas on the national highways and the CCTV recordings are being examined, he said.
There was no guard at the ATM booth when the loot took place, Rashtradeep said.
