Tens of thousands of women in West Bengal state marched through the streets on Wednesday night in protest against the rape and murder of a trainee doctor at a state-run hospital in Kolkata last week.

The Reclaim the Night march was the culmination of nearly a week of frenzied protests ignited by the brutal killing of the 31-year-old at the RG Kar Medical College last Friday.

After a gruelling 36-hour shift, she had fallen asleep in a seminar room due to the lack of a designated rest area.

The next morning, her colleagues discovered her half-naked body on the podium, bearing extensive injuries. A hospital volunteer worker has been arrested in connection with the crime.

Responding to calls on social media, women from all walks of life marched across Kolkata city and throughout the state on a rainy Wednesday night.

Though protests were largely peaceful, they were marred by clashes between the police and a small group of unidentified men who barged into the RG Kar Hospital, the site of the doctor’s murder, and ransacked the emergency department.
