A doctor and his mechanic friend have been arrested by the police in Ajmer, India, for allegedly robbing a nationalised bank. The doctor had taken a loan from a bank to set up a hospital but failed to run it, while the mechanic had returned to India with a loan on his head after working overseas. The duo robbed the bank using toy pistols and a fake dynamite box, demanding Rs 40 lakh but only managing to steal Rs 3.76 lakh.
