Police in southern Pakistan have shot dead a blasphemy suspect during an alleged shootout with armed men, in the second such killing in a week.

Police identified the slain man as Shah Nawaz, a doctor in the Umerkot district in the Sindh province, who had gone into hiding two days ago after being accused of insulting Islam’s Prophet Muhammad and sharing blasphemous content on social media.

Local police chief Niaz Khoso said Nawaz was “killed just by chance” on Wednesday night when officers signaled two men riding on a motorcycle to stop in Mirpur Khas, a city in the southern Sindh province.

He said instead of stopping, the men opened fire and tried to flee, prompting police to return fire. One of the suspects fled on the motorcycle, while the other was killed, he said.

Khoso claimed that it was only after the shootout that officers learned that the slain man was the doctor being sought by them for the alleged blasphemy.

Videos circulating on social media showed local clerics throwing rose petals at police and praising officers for killing the blasphemy suspect. There was no immediate clarification from the Sindh government about the circumstances in which the suspect was killed.

The killing of Nawaz drew strong condemnation from the country’s independent Human Rights Commission of Pakistan, or HRCP, which said it was “gravely concerned by the alleged extrajudicial killing of two people accused of blasphemy.”

“This pattern of violence in cases of blasphemy, in which law enforcement personnel are allegedly involved, is an alarming trend,” it said in a statement. HRCP also asked the government to conduct an independent inquiry to ascertain who was responsible for Nawaz’s death and ensure those responsible for it were punished.

The killing of Nawaz in Mirpur Khas came a day after Islamists in a nearby city, Umerkot, staged a protest demanding his arrest and burned his clinic.

The latest killing comes a week after an officer opened fire inside a police station in the south-western Pakistani city of Quetta, fatally wounding Syed Khan, another suspect held on accusations of blasphemy. Khan was arrested on Wednesday after officers rescued him from an enraged mob that claimed he had insulted Islam’s Prophet.

But he was killed by a police officer, who was quickly arrested.

However, the tribe and the family of the slain man said they pardoned the officer, saying Khan hurt the sentiments of Muslims by insulting Islam’s Holy Prophet Muhammad.

Though killings of blasphemy suspects by mobs are common, such killings by police are rare in Pakistan, where accusations of blasphemy – sometimes even just rumors – often spark rioting and rampage by mobs that can escalate into killings.

Under Pakistan’s controversial blasphemy laws, anyone found guilty of insulting Islam or Islamic religious figures can be sentenced to death – though authorities have yet to carry out a death sentence for blasphemy.

Pakistan has witnessed a surge in attacks on blasphemy suspects in recent years.

In June, a mob broke into a police station in the north-western town of Madyan, snatched a detainee who was a tourist, and then killed him over allegations that he had desecrated Islam’s holy book.

Last year, a mob in Punjab province attacked churches and homes of Christians after claiming they saw a local Christian and his friend desecrating pages from a Qur’an. The attack in the district of Jaranwala drew nationwide condemnation, but Christians say the men linked to the violence are yet to be put on trial.
