Imran Khan says 'probably my last tweet before my next arrest.'

Former prime minister and Pakistan Tehrik-e-Insaf (PTI) Chairman Imran Khan on Wednesday invited all stakeholders to sit and talk while there was still time as he fears another arrest during a raid at his residence in Lahore's Zaman Park.

Imran said that police were surrounding his house in an upscale area of the eastern city of Lahore and he could be arrested.

"Probably my last tweet before my next arrest. Police have surrounded my house,” Imran wrote on Twitter handle while sharing live link to his address to party supporters on YouTube.

However, police said they were surrounding the home because dozens of people linked to last week’s violent attacks on public property and military installations were hiding there.

The development comes hours after Amir Mir, a spokesman for the Punjab provincial government, said Imran has 24 hours to hand over 40 suspects allegedly hiding at his home or face a police raid. He told a news conference that so far 3,400 suspects have been arrested and more raids were underway.

At a presser, Mir also made the big announcement that these suspects would be tried by the military courts. It means that they would be booked under the Pakistan Army Act for attacking military installations.

Mir said these criminals were involved in terrorism and attacks on the military installations during the May 9 protest of the PTI in different cities. He said that "technical and intelligence” information had also been received through geo-fencing that terrorists have sought refuge in Zaman Park residence of Imran Khan.

Pakistani authorities were pressing on with efforts to try civilians involved in recent anti-government protests before military courts despite appeals from a leading international rights group and a local watchdog.

Amnesty International and Human Rights Commission of Pakistan issued separate statements late on Tuesday, saying they were alarmed by the government's plan to bring supporters of Imran Khan who clashed with police and rioted across the country to trial under military rules.

Military trials in Pakistan are usually held behind closed doors, depriving civilians of some of their basic rights, including contracting a lawyer of their choice.

A wave of violence engulfed Pakistan's capital and other urban areas following the dramatic arrest of Imran Khan — now opposition leader —from a courtroom in Islamabad on Tuesday last week.

Angry Imran supporters torched buildings and vehicles and attacked police and military personnel and facilities. The clashes killed 10 people; authorities arrested 4,000. The Supreme Court later ordered Khan’s release and criticised the way he was arrested.

On Wednesday, a top court in Islamabad extended Imran Khan’s bail and protection from arrest until the end of the month.

The government of Prime Minister Shahbaz Sharif — who succeeded Imran after a no-confidence vote parliament ousted the latter last year — accused the former premier of hiding suspects linked to the attacks on military installations at his residence in Lahore, the provincial capital of Punjab.

Imran claimed in a tweet that his supporters, both men and women, detained by authorities are being tortured in police custody and demanded the immediate release of female protesters. He offered no evidence to back those claims.

The Pakistani army and government announced on Tuesday they will try "the arsonists” involved in the violent protests under military law.

Dinushika Dissanayake, Amnesty's deputy regional director for South Asia, said that trying civilians in military courts is contrary to international law.

The Human Rights Commission of Pakistan said civilians arrested should be tried in civil courts and not military ones - reserved for troops suspected of working against the country's national interests and violating military rules.

Dissanayake accused the Pakistani government of using military law as "an intimidation tactic, designed to crack down on dissent by exercising fear of an institution that has never been held to account for its overreach.
