The establishments were sealed in Sector 19 area.
“The sealed establishments were the ones that were served final notices by us to relocate or shut down, but they were still operating. All establishments of commercial nature being run in residential sectors or even in industrial areas, as well as those flouting other land-use norms, would be targeted,” the authority’s chief executive officer S.K. Dwivedi said.
The sealed bank branches include Vijaya Bank, State Bank of India NRI Branch, Indian Bank, Punjab & Sind Bank, Bank of Maharashtra and Andhra Bank.
On Thursday, the authority plans to seal illegal nursing homes, departmental stores and other shops.
Sources in the authority said the drive would continue for around a month.
The Supreme Court Dec 5, 2011 had directed the Noida Authority to get the residential areas of the city rid of all commercial establishments, and help them relocate to designated areas.
