Harmanjeet Singh, 22, was killed after an altercation with three Nihangs â€” a radical Sikh warrior sect known for dressing in blue robes, carrying swords, and a puritanical moral code.
The trio had accused Singh of being drunk and consuming tobacco â€” both prohibited under the religion's codes of conduct.
"The incident occurred in full public view," Amritsar police commissioner Arun Pal Singh told reporters Thursday, a day after the murder.
"Onlookers watched the entire episode at Kahia Wala Bazar on Wednesday night and did not come forward to prevent it." Police had arrested all three men by Friday afternoon, officers said.
The protection of shrines is a highly sensitive issue for the Sikh faith, and the consumption of tobacco, liquor or drugs on a holy site is considered an act of desecration.
The killing took place in a market just a few minutes' walk from the Golden Temple, the headquarters of the religion's most senior clergy and home of its holy book of scripture, the Guru Granth Sahib.Agence France-Presse
