The driver of a cash van who fled with Rs. 22.5 crore from southeast Delhi on Thursday evening was arrested by the police hours after the theft that is believed to be the biggest heist in the city. Pradeep Shukla was caught in a warehouse close to the place where the van was found abandoned last night. All but Rs. 11,000 have been recovered from him. Sources say he used this money to buy clothes and later slept at the warehouse with boxes containing the remaining cash.
