After she died this morning, her family members and colleagues went on a rampage dmaging furniture of the hospital's emergency unit alleging negligence by doctors.
Personnel from Tala police station rushed to the spot and one senior police officer and five constables, including two posted at the hospital were injured, the police said.
No suicide note was recovered from Halder's house and police have started a probe into the matter, police said.
