Arunima may undergo surgery

"During the examination of Sonu, who was admitted yesterday, it was detected that her amputated left leg has swelling and infection which may require further surgery for treatment," said the sources at Chattrapati Shahuji Maharaj Medical University, where Arunima was shifted yesterday.

As of now the dead tissues were removed, wound cleaned and fresh dressing was done, they said.

"Though her condition is stable, but due to excessive bleeding Sonu`s haemoglobin level has gone down fairly due to which transfusion was done last night," the sources said.

Sonu`s case is that of amputation below the knee and she has been kept in high-dependency ward, they added.

The 23-year-old player was earlier undergoing treatment at Bareilly district hospital where she was admitted on April 12, a day after being thrown out of the Padmavat Express by three men trying to rob her when she was travelling to Delhi to appear for an examination.

The police had lodged an FIR under section 307 (attempt to murder) and 393 (attempt to robbery) of the IPC.
