During his incarceration , Badat assisted British and US authorities with information on other alleged terrorists . Some of this information was used in the US prosecution of Adis Medunjanin , a suspect in a 2009 plot to attack the New York City Subway . Because of this co-operation , Badat 's sentence was cut from 13 years to 11 , and an order put in place banning reporting of this deal to police and the media due to concern for Badats ' safety until he was due to give evidence in public . In 2012 the British government revealed that Badat had been released from prison in March 2010 . Theresa May was questioned by Labour MP Keith Vaz about the deal which included the use of taxpayer money to rehouse Badat and provide an office space with phone and internet service . May defended the agreement citing that " Crown Protection Services have said that they considered very carefully the merits of entering into this agreement with a convicted terrorist , that they believed the administration of justice would actually benefit from the agreement they entered into " and that " co-operation is obviously a long-standing feature of our criminal justice system " . Saajid Badat also gave evidence ( via video-link from his secret hiding place in UK ) in March 2014 at the trial in New York of Sulaiman Abu Ghaith ( Osama bin Laden 's son-in-law ) , during which he testified that instructions were given to him during his time in Afghanistan ( 2001 ) to give shoe bomb to a group of 4 to 5 Malaysian terrorists , one of them the pilot . And Badat provided them one of his own shoe bomb . Badat and Malaysian terrorists discussed the possibility that the cockpit door in airliner might be locked : " So I said : ' How about I give you one of my bombs to open a cockpit door ? ' " One possible target of Malaysian terrorist plot ( masterminded by Khalid Sheikh Mohammed ) would be the Petronas Towers in Kuala Lumpur , the world 's tallest buildings from 1998 until 2004 . These Malaysian Islamist 's connections with Badat and Al-Qaeda were uncovered just a few days after MH370 disappearance . The link was spotted by British media on 15 March 2014 . This idea were discussed later in a few newspaper but only until 19 March 2014
