YSR Congress chief YS Jaganmohan Reddy had dismissed the accusations against the lawmaker as politically motivated.
But CCTV footage has now emerged which shows the manager being pushed around and threatened by the politician and at least a dozen supporters. The incident happened on November 26.
According to the complaint filed by Mr Rajasekhar, Mithun Reddy, who represents Rajampet constituency in Kadapa district, shouted at him before slapping him. The official alleged that Mr Reddy, along with some of his supporters, later barged into his cabin and misbehaved with him.
Charges against Mr Reddy, who is absconding, have been revised based on the manager's medical report and the CCTV footage; the lawmaker has now been booked for extortion, among charges, which attract a maximum punishment of 10 years in jail.
Four people, including a YSR Congress legislator CH Bhaskar Reddy, had been arrested last month but were released bail.
