An accountability court on Tuesday handed over former President Asif Ali Zardari to the National Accountability Bureau on 10-day judicial remand.
The PPP co-chairman who was arrested by the Bureau yesterday after Islamabad High Court rejected his bail plea in mega money laundering case.
Zardari was produced today before NAB amid tight security arrangements.
Zardari has previously spent time in jail on corruption charges, but was president from 2008 until 2013.
He was elected to office after the assassination of his wife, former Prime Minister Benazir Bhutto.
Zardari has long been considered one of the most controversial figures in Pakistani politics. He spent time in jail in the 1990s and 2000s, and was nicknamed “Mr 10%” for the commissions on government contracts he allegedly received.
Investigators say fake bank accounts were used to funnel billions of rupees. Dozens of companies and hundreds of people have been implicated in the scandal, according to Pakistani media reports.
Zardari denies wrongdoing in this latest “fake accounts” case, which has been under investigation since 2015.
He and his sister, lawmaker Faryal Talpur, had their interim bail extended multiple times before Monday’s decision.
Both attended court earlier on Monday under tight security conditions, but Ms Talpur has not yet been taken into custody.
Pakistan’s interior minister, Ejaz Shah, told parliament on Monday that the government had no role in Mr Zardari’s arrest.
A party spokesman has appealed for PPP supporters to remain peaceful.
