On Saturday night, Atiq Ahmed, a former Indian politician who had been convicted of kidnapping, was shot dead on live television along with his brother.
Ahmed was talking to reporters in Prayagraj, also known as Allahabad, when a gun was pulled close to his head and he was shot.
Three men posing as journalists quickly surrendered and were taken into custody.
Ahmed's teenage son had been shot dead by police a few days earlier, and Ahmed had claimed that there was a threat to his own life from the police.
Ahmed had been under police escort at the time of his shooting. Ahmed had been involved in dozens of cases over the past two decades, including kidnapping, murder, and extortion.
He was sentenced to life in jail earlier this year in a kidnapping case, along with two others.
The incident has sparked outrage in India and raised questions about the security provided to high-profile prisoners.
The shooting has also raised concerns about the use of violence in Indian politics and the criminalization of politics in some parts of the country.
