The incident had angered UP Chief Minister Yogi Adityanath, who ordered DGP Sulkhan Singh to take prompt action in the case. Four police officials were suspended after the killings.
"... the rule of law will prevail in Uttar Pradesh. There will be absolutely no protection for criminals in the state," the Chief Minister, whose party BJP stressed on a crime-free UP during their poll campaign, had said.
In the CCTV footage of the incident, a man with his face covered opens the door and points a gun at the men inside the shop. More robbers follow, their face masked by helmets, and a fight ensues as the staff tries to push them back.
Jewellers across the state observed a day-long strike yesterday to protest the lack of action in the case. The Lucknow Sarrafa Association had also submitted a memorandum to state minister Shrikant Sharma demanding adequate security for jewellers in Uttar Pradesh.
The opposition parties attacked the Adityanath-government for the degradation of law and order situation in UP.
Last week, in the Chief Minister's hometown Gorakhpur, a 45-year-old trader was stopped on his way home by bikers who shot him dead and fled with around Rs 8 lakh.
