Senior BJP leader Sushma Swaraj attended the funeral of Raj Bala, who allegedly sustained spinal injuries in police action during Ramdev's fast at Ramlila Maidan on June 5, in Haryana's Sonepat district on Tuesday.
"After battling between life and death for 15 weeks, Raj Bala died. It is a sad commentary on our Police functioning," Swaraj tweeted on Monday.
The leader of opposition in the Lok Sabha said Union minister Kapil Sibal had claimed that not a single lathi was used and no one was injured in Ramlila Maidan during police action on Baba Ramdev and his supporters.
"Will he now explain to the nation? I demand that a murder case be registered against Delhi Police and the guilty must be punished," Swaraj said on Twitter.
Raj Bala died of cardiac arrest 114 days after she was admitted to GB Pant Hospital for treatment of spinal injuries.
Though doctors tried to revive her for more than an hour, her organs stopped responding.
Bala, a Gurgaon-based yoga instructor who also had been a former councillor of the Gurgaon Municipal Council, had suffered fracture and dislocation of cervical vertebraes with paralysis of all four limbs after the midnight crackdown on Ramdev's supporters.
The family have alleged that Bala received injuries during the police lathicharge, but the doctors claim that she had been suffering from Osteoporosis, which results in the thinning of bone tissue and loss of bone density.
"For such people, even a slight fall can result in fracture. It cannot be said whether it was lathicharge or the following stampede that caused the injury," said one of the doctors.
The Delhi Police have also denied the family allegations. The family, however, wants a thorough investigation in the matter.
In her three months in the hospital, Bala underwent three surgeries.
In a statement, Ramdev termed the death as an 'ultimate sacrifice' in the second freedom struggle.
Bala was planning to contest municipal corporation of Gurgaon elections from her ward.
