The lawyer of one of the accused, Uttkarsh Vinod Pande, said that his client was innocent and allegation levelled against him a wrong.
"They are making a false allegation on my client Uttkarsh Pandey. He was not present at the time of the incident, so he is not responsible for this. He was not even present near the vicinity of the incident spot," advocate Sayaji Nangre said.
