Rahami's reportedly attended jihadi training camps in Pakistan along with his brother on numerous occasions, allegedly becoming radicalised by Islamist extremists. The 28-year-old’s brother Mohammad and sister, Aziza, have also posted pro-ISIS material on Facebook supporting the so called caliphate and renouncing democracy.

His mother's whereabouts are also unknown after she apparently travelled to Turkey just three days before the pipe bomb attacks, prompting claims she knew about the bombings before hand. The brothers are seen in a picture dated April 2013, during one of Rahami's lengthy trips to Pakistan where it is believed they attended radicalisation camps and were schooled in how to become jihadis.

Just days later Mohammad posted a pro jihadi video on social media, as did Aziza – who calls herself Masood Maymunah on Facebook. It is not clear whether the siblings are currently in America as it is believed they could be in Turkey, Syria or Egypt.

Evidence of Rahami's radicalisation during his lengthy foreign trips has been supplied by locals in Elizabeth, New Jersey, who say he suddenly began wearing traditional Islamic dress after returning from Pakistan in 2014. Rahami was arrested after a shootout with police and charged with five counts of attempted murder and firearms offences.
