Three men have been arrested for their alleged involvement in the attack on a Delhi-based businessman here after a failed Rs 1.5 crore robbery attempt, police said Friday. The three, who work in a company linked to the businessman in Sector 57 here, was identified after the police scanned footage of at least 18 CCTV cameras and found a modus operandi "rarely" used in Noida, a senior official said.

Delhi's Gagan Vihar-resident Sunil Khanna was attacked by the assailants on January 7 near NIB road in the industrial area of Sector 62 at around 4.30 pm with the attackers vandalising his car and opening fire at him, Noida 2nd Circle Officer Rajeev Kumar said. "Khanna, however, escaped unhurt as a crowd gathered at the spot in the busy area and the robbery attempt failed because coincidentally he was not carrying any money that day.
