Rao, who is accused of forging land documents of Green Field venture at Neredmet here, for illegal gains, was taken by police from his house at Musheerabad for examination, a senior police officer told PTI denying reports that he was arrested.
"He is being taken by police to Neredmet police station for examination in connection with the case and so far the arrest has not been effected," the officer said.
In November 2011, a criminal case was registered against Shanker Rao, his brother P Dayanand and three others for allegedly duping the owners of housing plots in Green Field Colony.
Residents of the Green Field Colony, in a petition filed before the Andhra Pradesh High Court, had earlier alleged that the former minister and others encroached upon the land of their colony.
Police wanted to question him in connection with the case after the High Court lifted the stay on his arrest last year.
In November last year Rao underwent a bypass surgery and was later discharged.
