Kolkata: Police arrested one person for his alleged involvement in the sexual assault and murder of a woman postgraduate trainee doctor at the state-run RG Kar Medical College and Hospital, a senior officer said on Saturday.
The arrested man, an outsider had free access to the different departments of the hospital, he said.
"We have arrested one person, who is an outsider. His activities are quite suspicious and he seems to be directly involved in the crime," the police officer told PTI.
Talking more about the arrested accused, police said that they recovered a torn part of a Bluetooth earphone which led to the culprit.
In fact, other PGTs and female doctors also identified the culprit from CCTV footage grabbed from other parts of the hospital premises, a source in the police department said.
Police officers also claimed that the arrested accused had given different statements during the grilling done.
"Now, we are trying to find out who else was with him or he had someone else with him," he said, adding that police might conduct necessary medical examinations on him.
Police officers also questioned two intern doctors the entire Friday night in connection with their ongoing probe into the death of the woman doctor, he said.
The semi-nude body of a woman postgraduate trainee (PGT) doctor was found inside the seminar hall of the government-run hospital in Kolkata on Friday.
The deceased, a second-year student of the chest medicine department, was on duty on Thursday night. The body bore injury marks.
Her father had alleged that she was raped and murdered inside RG Kar Medical College and Hospital and efforts are on to hide the truth.
Preliminary autopsy report has indicated sexual abuse of the woman doctor before she was killed, police said.
