Indian police have shot dead four men suspected of raping and killing a young female vet in Hyderabad last week.
The men were in police detention and were taken back to the scene of the crime in the early hours of Friday.
The suspects were shot when they tried to steal the officers' guns and escape, police told BBC Telugu.
The 27-year-old victim's charred remains were discovered last Thursday – and the case sparked outrage and protests over alleged police inaction.
The police were heavily criticised after the murder – particularly when the victim's family accused them of inaction for two hours.
Cyberabad police commissioner VC Sajjanar told BBC Telugu that police took the accused to the scene to reconstruct the crime.
Two police officers were injured when the men tried to escape, he said. News of the police action has been widely celebrated on social media.
Many took to Twitter and Facebook to applaud the police, saying they "delivered justice".
The mother of a student who died after being gang-raped on a bus in capital Delhi in 2012 has also hailed the killing.
"I am extremely happy with this punishment. Police have done a great job," she told ANI news agency.
BBC Telugu reporter, Satish Balla, is at the spot of the encounter, where approximately 2,000 people have gathered, causing a huge traffic jam.
Vehicles have come to a standstill on the highway, where people are shouting "hail the police" slogans.
But a few have also questioned the police action.
Prakash Singh, a retired police officer and a key architect of police reforms, told the BBC that the killings were "entirely avoidable".
"Abundant caution should be taken when people in custody are being taken to the court or the scene of the crime," he said.
"They should be secured, handcuffed and properly searched before they are taken out. All kinds of things can happen if the police are not careful."
But Mr Singh said it was too early to say if the incident was an extrajudicial killing – known popularly in India as an "encounter killing".
In the days after the rape and murder, thousands of people protested at Hyderabad police station, insisting the killers face the death penalty.
Elsewhere in the country, there were other protests and vigils for the victim, who cannot be named under Indian law.
Last week, three police officers were suspended when the victim's family accused them of not acting quickly enough when the woman was reported missing.
Officers had suggested she may have eloped, relatives told the National Commission for Women, a government body.
