The second autopsy of Comilla college student Sohagi Jahan Tonu has found evidence of "sexual intercourse", doctors said.

Dr Kamoda Prosad Saha, head of Comilla Medical College Hospital's forensic department who headed Tonu's second autopsy, confirmed it to The Daily Star.

“The body was highly decomposed so the cause of death could be determined by circumstantial evidences and further investigation,” Dr Kamoda Prosad said.

The first “controversial” autopsy conducted on March 21 was rejected by Tonu's parents as it could not ascertain the reason for her death or find any symptoms of rape.

As per a court order, Tonu's body was exhumed on March 30 and the medical board was formed with Dr Kamoda Prosad as its chief for the second autopsy.

Tonu was a second year history department student of Comilla Victoria College. Her body was found about 400 yards from her house inside Comilla Cantonment on the night of March 20, according to her family members.

The murder of Tonu created a huge uproar of protest throughout the country.
