Yakub Memon, the lone convict sentenced to death in the 1993 Mumbai serial blasts case that killed at least 257 people , was hanged to death at Nagpur central jail on Thursday at around 7 am, two hours after the Supreme Court rejected his final plea in a dramatic legal tussle.

Memon was sent to the gallows on his 53rd birthday.

Reports said Yakub's body will be handed over to his family after the jail authorities complete the postmortem procedure and other formalities. His body will be brought to Mumbai for burial. Heavy security arrangements have been put in place across the sensitive areas of Mumbai to thwart any protests.

According to reports, Yakub was woken by jail authorities around 4 am, permitted to bathe and offer prayers, before he was led to the gallows. Hindustan Times reported that the constable who executed 26/11 attacks convict Ajmal Kasab at Pune’s Yerawada jail in 2012 carried out the execution, while the rope was sourced from outside.

Additional DGP Meeran Borwanar, jail superintedent Yogesh Desai, a medical officer and few others were present at the hanging yard. This was the 21st hanging at the Nagpur central jail since independence.

A three-judge panel rejected the last-minute petition clearing the last judicial barrier to executing Memon.

The Supreme Court had last week rejected his one appeal, but Memon again approached the court arguing that the 'order to hang him' was passed but he still had legal recourse available.

A two-judge Supreme Court bench on Tuesday, July 28, gave a split verdict and referred Memon's mercy plea to a larger bench of justices. Supporters of Memon's plea said he cooperated with investigating agencies and that he was the only person of several convicted to face the death penalty for the bombings, which targeted separate landmarks that killed at least 257 people in Mumbai, then known as Bombay.

Police consider Memon's brother Tiger Memon and mafia don Dawood Ibrahim to be the main masterminds behind the attack carried out to avenge the destruction of an ancient mosque by Hindu zealots in 1992. Both remain in hiding, reportedly in Pakistan.

Others originally charged in relation to the attack had their sentences reduced to life imprisonment in 2013. But Memon was found by the court to be the 'driving spirit' behind the attacks, and his 2007 death sentence was upheld.

While Tiger Memon has remained in hiding since 1993, Yakub Memon decided to return to India from Pakistan in 1994, protesting his innocence. He was detained shortly afterwards in circumstances that remain unclear: he had said he turned himself in, but police claimed an arrest.

Memon was born in Mumbai on July 30, 1962, and attended Antonio D'Souza High School. He completed a Masters in Commerce and Arts at the Burhani College of Commerce and Arts. After his four-year study at Institute of Chartered Accountants of India, Memon went on to become a chartered accountant in 1990.
