The United Arab Emirates (UAE) handed over Muttahida Qaumi Movement’s Hammad Siddiqui , accused in the Baldia Town factory fire, to Pakistani authorities.

The blaze, which had erupted at Ali Enterprises in Karachi's Baldia Town on September 11, 2012, had devoured lives of over 250 labourers.

According to reports, Siddiqui has arrived in Pakistan and is in the custody of intelligence agencies, his deportation was conducted not through standard operating procedures but by mutual intelligence coordination between Pakistan and UAE .

In October, Hammad Siddiqui was arrested in Dubai and local authorities had approached the Pakistani Consulate for his extradition.

An anti-terrorism court (ATC) had last year ordered Pakistani authorities to have Siddiqui who is the former in-charge of MQM’s Karachi Tanzeemi Committee arrested through Interpol.

The Ministry of Interior, acting on the court orders, had also issued a red warrant for Siddiqui.

In Dec 2016, another key accused in the Baldia factory fire case, Abdul Rahman alias Bhola, was arrested from Bangkok, Thailand, by the Interpol.

The key suspect behind Pakistan's deadliest industrial fire had confessed that he deliberately set fire to Ali Enterprise on the instructions of MQM leader Hammad Siddiqui .

Bhola had revealed that the MQM leader instructed him to set fire to the factory in the vicinity of Baldia Town Karachi because of non-payment of Rs 250 million 'bhatta (protection money)'.

He had claimed the intent behind the arson attack was only to intimidate owners of the factory, and he didn’t anticipate that his act would result in the loss of lives.
