Environmentalist Sunita Narain, who was admitted to AIIMS after being hit by a vehicle while cycling in Delhi on Sunday morning, is in a stable condition.
The Centre for Science and Environment (CSE) issued a bulletin saying its director-general Narain was stable and recovering after surgery.
"Doctors say she (Narain) is now stable and recovering after a surgery was done later on Sunday to implant two titanium rods in her arms. The nose required sutures, and may need some corrective surgeries later," said the CSE statement.
"Cyclists in Indian cities are being edged out systematically to make way for cars - sometimes literally so. CSE director general Sunita Narain was hit by a car while on her daily cycling run on Sunday morning near Delhi's All India Institute of Medical Sciences. She suffered fractures on both her arms and her nose."
Narain and CSE have been vocal supporters of people's right to walk and cycle on the roads of urban India.
The accident took place around 6.15am while Narain was cycling from her house in Green Park to Lodhi Park.
She was hit by an unidentified vehicle near the AIIMS flyover and was rushed to the AIIMS trauma centre.
Police have registered a case of causing injuries due to rash and negligent driving, and are trying to identify the vehicle.
However, police are yet to record Narain's statement as she underwent a nine-hour surgery. Her statement would be helpful in identifying the vehicle, police said.
