The officials also reclaimed the car park area and a park nurtured by the Daya Cyber Park as part of the demolition drive carried out with police escort.
The compound wall of a neighbouring building was also pulled down as it was also built on encroached land, officials said.
The action was taken after an inquiry by civic officials found that Daya Cyber Park and the neighbouring building had encroached around 5.5 cents (one cent is around 436 sq feet) and 1.5 cents respectively in two survey numbers, they said.
The Daya Cyber Park itself, located on a 3.18 acres site, had faced civil litigation over ownership. While it was claimed that the land belonged to a trust, the company maintained the sale of land had been effected legally and related cases disposed of by court.
