They were arrested from Lahore airport.
It has been learned that Nawaz Sharif and Maryam Nawaz have been detained by the NAB officials. The duo courted arrest peacefully and cooperated with the authorities.
Their passports have been confiscated and they will be taken to Islamabad later, either by a chopper or a private jet depending on the weather conditions.
Earlier, the Pakistani Court on July 6 sentenced former Pakistan Prime Minister Nawaz Sharif to 10 years in prison on corruption charges related to four luxury hotels in London.
The National Accountability Bureau (NAB) court gave the verdict after a series of delays
The court also gave 7 years jail term to Maryam Nawaz Sharif, daughter of Nawaz Sharif and one-year jail term to Safdar Awan, son-in-law of Nawaz Sharif.
After the verdict, Nawaz Sharif has called the charges as politically motivated. Both Nawaz Sharif and daughter Maryam Nawaz Sharif are in London where Kulsoom Nawaz, wife of Nawaz Sharif, is receiving cancer treatment.
Judge Mohammad Bashir ordered Sharif to serve 10 years for owning assets beyond income and one year for not co-operating with the NAB. He will serve his sentences concurrently.
Daughter Maryam received seven years for abetting a crime and one year for not co-operating again to run concurrently while Safdar Awan`s sentence is for not co-operating.
The case, known as the Avenfield Reference, relates to a number of properties in the UK capital.
The Panama Paper leaks’ 2015 revealed that several of Sharif`s children had links to offshore companies, which were allegedly used to channel funds and buy foreign assets - including luxury flats in Avenfield House, on London’s Park Lane.
However, his family insists that legitimately acquired the four properties.
As part of the ruling, the court ordered they be confiscated for the federal government.
Meanwhile, the court repeatedly delayed the decision, initially pushing the ruling back after Friday prayers and then several times again, sparking speculation about the wait.
However, the judge reportedly said part of the delay was because of the need to photocopy the judgment - which is more than 100 pages long - for both the defense and the prosecution.
The ruling comes just a few weeks before Pakistan`s general election on 25 July. Sharif is disqualified from standing for his center-right party, the PML-N.
