Oli, 74, who resigned after the unrest, was taken into custody along with former home minister Ramesh Lekhak following a recommendation by an official panel that they be prosecuted over their handling of the violence.

Police spokesman Om Adhikari said both men were being held at the Kathmandu Police Office and would be produced before a court on Sunday.The arrests come a day after rapper-turned-politician Balendra Shah was sworn in as prime minister, marking a shift in Nepal’s political leadership after elections influenced by public anger over the deaths.

Authorities said the detentions were made in line with the findings of a commission that examined the September protests, during which 76 people were killed over two days of unrest.

The panel held Oli responsible for failing to act to halt prolonged firing that killed at least 19 Gen Z protesters on the first day.“We have arrested them as per the recommendations made by the investigation commission,” Adhikari said.

Oli was later transferred to a hospital from police custody, witnesses said, citing his health condition. He has undergone two kidney transplants in the past.

Oli’s lawyer, Tikaram Bhattarai, said the arrest lacked legal basis, arguing there was no risk of his client fleeing or evading questioning.“They have said it is for investigation. It is illegal and improper,” Bhattarai told Reuters.

Lekhak and his legal representatives were not immediately available for comment.political falloutThe deaths during the protests became a central issue in Nepal’s recent elections, helping propel Shah’s Rastriya Swatantra Party to a landslide victory.

The demonstrations, largely driven by younger voters, were fuelled by allegations of corruption and demands for accountability.Oli’s arrest underscores the new administration’s apparent willingness to act on the findings of the investigative panel and pursue legal accountability for the violence.

The findings come two days before rapper-turned politician Balendra Shah is set to be sworn in as prime minister after securing a landslide victory in parliamentary elections triggered by the unrest.

The 970-page report held Oli, 74, responsible for not intervening during hours of firing on the first day of youth-led demonstrations, in which at least 19 Gen Z protesters were killed. Overall, 76 people died and 2,522 were injured during two days of violence, the panel said, broadly aligning with earlier government estimates.

“As the executive head Oli should be held responsible for anything good or bad,” the report stated.The panel also recommended prosecution of former home minister Ramesh Lekhak and then police chief Chandra Kuber Khapung, citing their roles in the handling of the crackdown.

None of the individuals named could be immediately reached for comment.Legal experts said the panel’s findings do not constitute formal charges and must be followed by a criminal investigation before any case is brought to court.“It is not a charge sheet and they cannot be jailed on the basis of this report,” said senior lawyer Dinesh Tripathi.

“There has to be a criminal investigation by police … The government can file the case in the court only after that.”If prosecuted and convicted, those named could face prison terms of up to 10 years, according to the report.

Analysts say the decision on whether to act on the recommendations now rests with Shah, 35, and his Rastriya Swatantra Party, which rose to power on the back of anti-corruption sentiment following the protests.

The panel also called for action against dozens of other officials and security personnel involved in the crackdown. Families of victims have continued to demand accountability for the deaths and injuries during the demonstrations.
