The brother of Pakistani social media star Qandeel Baloch has confessed to killing her "for honour", police said.
"The police arrested Muhammad Wasim, brother of Qandeel Baloch, for killing his sister late on Saturday," Multan City police chief Azhar Akram said.
"Wasim confessed to his crime, saying he killed his sister for honour after her recent objectionable videos, mostly posted on Facebook."
Wasim told police he drugged his sister and then strangled her, police said.
Baloch rose to fame for her provocative Facebook posts that saw her praised by some for breaking social taboos but condemned by conservatives.
She was killed on Friday night at her family's home near Multan and her body was discovered on Saturday.
Wasim went on the run and was arrested late Saturday in neighbouring Muzaffargarh district.
"I have no regrets," he told journalists in a press conference arranged by the police early on Sunday.
Outpouring of grief
The killing sent shockwaves across Muslim Pakistan and triggered an outpouring of grief on social media for Baloch, whose real name was Fauzia Azeem.
More than 500 people — almost all women — die in Pakistan each year in such killings, usually carried out by members of the victim's family meting out punishment for bringing "shame" on the community.
Waseem said he killed his sister due to her social media activities, which included a series of posts with a prominent Muslim cleric, Abdul Qavi.
One video shows her sitting on the cleric's lap.
Abdul Qavi, who was suspended from a prominent Muslim council in the controversy following the posts, told local media after Baloch's death he had "forgiven her" and the matter was now in God's hands.
After Baloch's death, many Pakistanis again called for the passage of an anti-honour killing law, aimed a closing a loophole that allows family members to forgive the killers.
"The death of Qandeel Baloch conveys an insidious message: that women will be kept back at all cost; murdered, if they dare nurture ambitions to break the glass ceiling," the English daily Dawn newspaper wrote in an editorial on Sunday.
"Her murder ... must serve as an impetus for legislators to renew demands for legislation to protect women who are threatened under false notions of 'honour'."
Baloch described as Pakistan's Kim Kardashian
Baloch, who called herself a modern-day feminist, was described as Pakistan's Kim Kardashian and built a modelling career on the back of her social media fame.
"As women we must stand up for ourselves. As women, we must stand up for each other," she told her 758,000 followers on Facebook, days before her death.
Earlier this year, Baloch offered to strip if the wildly popular Pakistani cricket team beat arch rival India.
She also appeared in a music video, gyrating bare legged to an Urdu-language song in high heels and a see-through top.
Prior to her death, Baloch spoke of worries about her safety and had appealed to the Interior Ministry to provide her with security for protection.
No help was provided and the Interior Ministry has not commented on her death.
On social media, some celebrated her killing as she had been a "disgrace" to Pakistan's culture.
But many grieved her death, saying she had helped the cause of women in a society where they are often banned from working or even appearing in public in ultra-conservative areas.
