The arrest of Kalyan Bainsla is likely to be followed by further questioning and investigation by Gurugram Police.
The police will examine CCTV footage, witness accounts and the videos circulating online as they piece together the events leading up to the collision.
The central points of dispute remain whether the car was deliberately moved towards Sia’s motorcycle and whether the collision was an intentional act or an accident, as Bainsla claims.
Sia has alleged that she was chased and deliberately rammed, while Bainsla has maintained that he lost control near a U-turn.
The addition of Section 109 of the BNS means the case is now being investigated with an attempt-to-murder allegation, rather than only as a case of rash driving and causing hurt.
However, the case is also about the wider question of how safe women are on the roads of Delhi and Gurugram.
Sia has said she will continue to pursue the matter and wants strict punishment when the allegations against Bainsla are proved.
The investigation and subsequent legal proceedings will establish what exactly happened on Golf Course Road on Sunday.
