Nepal ex-PM Oli gives defiant message after release from custody

Lekhak was also released from custody on Thursday, police said. Neither man has been formally charged, and both deny responsibility for the violence.

"Although the government filed a criminal case with prejudice and vindictiveness and illegally detained me... I have finally been released after not having enough grounds and evidence to prosecute," 74-year-old Oli said in a statement posted on social media.

The arrests came after an inquiry commission recommended prosecuting Oli -- a four-time prime minister -- and other officials for failing to stop security forces from opening fire on demonstrators.

The commission's report said statements given by the two men suggesting they did not know about the violence were part of a bid to shift responsibility and amounted to "criminal negligence".

Oli was taken to hospital soon after his arrest for what police described as a procedural check-up, adding that he suffers from heart and kidney problems.

"Due to my health condition, I will remain in the hospital for a few more days for treatment," Oli added.

"At this moment, I extend my heartfelt thanks to all party leaders, cadres, and well-wishers for their goodwill and support."

- 'Vengeful' -

After their arrests, their wives filed habeas corpus petitions at the Supreme Court, challenging the legality of their detentions.

"Both former prime minister KP Sharma Oli and the former home minister have been released today on the condition that they will present themselves to the police when required," Kathmandu Police spokesperson Pawan Kumar Bhattarai told AFP.

Oli's CPN-UML party has described the arrests as "a vengeful act" and called for protests.

The youth-led uprising in September began in Kathmandu and was triggered by a brief social media ban.

It spread countrywide the following day, fuelled by longstanding frustration over corruption and economic hardship.

Protesters set fire to the parliament building and offices and eventually toppled the government.

In a separate case, Nepal has issued an arrest warrant for former prime minister Sher Bahadur Deuba for alleged corruption, officials said Thursday.

Deuba, 79, is abroad for medical treatment and said that "an investigation on money laundering has been initiated against me and my family". He rejected the accusation of corruption.

"False propaganda is being spread concerning my family's property," he said in a statement on social media.

Authorities also issued a warrant for Deuba's wife, former foreign minister Arzu Rana Deuba, court officials in Kathmandu told AFP, following a request from the Department of Money Laundering Investigation.

Deuba said he and his wife were "currently abroad for long term medical treatment", without giving further details.

Former energy minister Deepak Khadka was also arrested last month as part of a money laundering investigation.
