Pakistan's former prime minister Nawaz Sharif and his daughter Maryam were arrested tonight and flown to Islamabad soon after they returned to the country following their conviction in one of the three corruption cases against the powerful political family, less than two weeks before the July 25 polls.
According to an airport official, the father-daughter duo surrendered before a team of the country's anti-graft body - The National Accountability Bureau (NAB) - without any resistance.
NAB had requested the court to condone their presence due to security reasons.
Maryam may be moved to Sihala Rest House on outskirts of Islamabad where security has been beefed up. The rest house will be declared as sub-jail.
The Etihad Airways flight EY243 arrived in Lahore from Abu Dhabi. Earlier Sharif and Maryam flew to the UAE capital from London, where Sharif's wife Kulsoom, suffering from throat cancer, is battling for her life.
Sharif reportedly refused to sit in the vehicle of the Rangers to get to the airport terminal. Federal Investigation Agency (FIA) officials took their passport for immigration.
According to media reports, dozens of security officials entered the plane after it landed and asked other passengers to leave. The duo's passports were seized by a three-member FIA team, and both were permitted to meet Begum Shamim Akhtar, Sharif's mother, in the Haj Lounge.
The two were convicted on July 6 in the Evenfield properties case linked to the Sharif family's ownership of four luxury flats in London.
Both Sharif, 68, and Maryam, 44, have been sentenced by an accountability court to 10 and 7 years in prison respectively.
The Sharif family is now facing two more corruption cases in the accountability court Al-Azizia Steel Mills and Flagship Investments in which they are accused of money laundering, tax evasion and hiding offshore assets.
Sahrif and Maryam were later sent on a special private plane bound for Islamabad International Airport. Upon landing at the Islamabad airport, they will either be flown to Adiala Jail or driven to Attock Jail, Dawn newspaper reported.
Sharif's PML-N party, led by its President and Sharif's younger brother Shahbaz, today managed to take out a rally despite imposition of section 144 that bars assembly of more than five people.
Earlier, media reports and an official of the Civil Aviation Authority had said their plane was diverted to Islamabad to avoid any law and order situation in Lahore as a large number of the PML-N workers were heading in hundreds of vehicles to the city to cheer up their leader.
The rally kicked off at the Lohari Gate in the afternoon and could manage to proceed a few kilometers as party workers struggled to remove cargo containers on their way.
Close to the airport, Sharif's supporters clashed with police which otherwise did not stop them from removing containers.
"It appears the Punjab caretaker government had reached a deal with the of PML-N withdrawing thousands of policemen to give a free hand to reach close to the Lahore airport and wind up the rally," a senior police officer told PTI.
"We have orders from our top command not to take action against the PML-N rally participants," he said.
The PML-N workers joined in the rally from different points in Lahore.
Talking to reporters before reaching the airport, Shahbaz said "a sea of people" has turned up today to give historic reception to Sharif.
"The people of Lahore has given a verdict ahead of July 25 polls," he declared. "I am thankful to the people of Lahore for coming out in such a huge number," he said, adding that the people have rejected the decision of the court to convict Sharif and Maryam.
Speaking to the BBC at Abu Dhabi airport as he waited to change planes, Sharif said: "What credibility will these elections have when the government is taking such drastic action against our people and this crackdown is taking place all over the country?"
In a video message, tweeted by Maryam, the former premier urged his followers to stand with him and "change the fate of the country".
"The country is at a critical juncture right now," a grim looking Sharif said.
Sharif was disqualified by the Supreme Court last year in the Panama Papers case.
Sharif has been one of the country's leading politicians for most of the past 30 years. He remains popular, especially in Punjab, the most populous and electorally significant province.
