A radical Hindu religious leader, Sudhir Suri, has been shot dead in northwest India.
The 58-year-old was killed on Friday while protesting in Amritsar, home to the famous Golden Temple, one of Sikhism’s holiest sites.
Mr Suri was the self-proclaimed leader of the fundamentalist religious group, Hindu Shiv Sena.
Authorities said a local shopkeeper was later arrested in connection with the murder.
Punjab State Police Director General Gaurav Yadav said the suspect was being questioned.
“Whoever is behind it, and whoever hatched the plot will be exposed, and those behind it will be arrested,” he said.
Sikhs in India and abroad have previously accused Mr Suri of derogatory comments about their faith and community.
According to the police, Mr Suri had gone to Amritsar in front of a local temple to protest against the alleged desecration of Hindu deities.
In recent years, Amritsar has seen a spate of apparently religiously motivated killings.
In September, a man was publicly killed after being accused of chewing tobacco and drinking near the Golden Temple.
Last year a man was beaten to death after he was suspected of attempting to commit an act of sacrilege near the temple.
