HA was returned to the UK on 17 th July 2019 as a result of extradition proceedings brought by the Crown Prosecution Service supported by Operation Manteline. 141 The investigators recovered 29.26kg of metal nuts. A further 1.47kg of screws or cross dowels were also recovered. The investigation concluded that there were approximately 3,000 such items of shrapnel in total. 143

Despite numerous arrests in the UK, no other individual other than Hashem Abedi has ever been prosecuted for their involvement in the bombing, including those who bought chemicals for Salman via the internet. The report said that had adequate action been taken, his return would have been taken "extremely seriously". (UGC/FAMILY)In this regard, I note that the instructional video I considered at paragraphs 23.7 to 23.10 did not include any reference to a switch. This is consistent with a switch being added to the design of the device at a later stage. It is a reasonable inference that this was probably after the TATP had been manufactured in accordance with the instructions in that video, which took place prior to the departure for Libya on 15 th April 2017.

Sir John said he does not accept Abdallah’s description of himself as a “normal Islamic Muslim person who lives in the West”. At 01:58 on 23 rd May 2017, a Halifax bank card bearing SA’s name was discovered in the City Room by the Operation Manteline Bomb Scene Manager, Robert Gallagher. It was logged on a GMP system at 02:20. 133 Vi har et stort udvalg af drikkedunke fra Sistema. Her har Sistema også været kreative og har lavet mange smarte og funktionelle drikkedunke. The delay in providing the report led to the missing of an opportunity to take potentially important investigative action," he concluded. The report stated: "We cannot know what would have happened, but there is at least the material possibility that opportunities to intervene were missed." Convicted terrorist Abdalraouf Abdallah played a key role in radicalising Abedi (PA)As I have explained in paragraphs 23.7 to 23.10, I am satisfied that SA and HA are likely to have watched the bomb‑making video identified by Operation Manteline, or one very like it. However, in my view, that in itself is not capable of being a complete explanation for the full extent of their knowledge. Ismail Abedi, 28 - who now calls himself Ishmale ben Romdhan - was aware of the hearing and had been given the opportunity to attend. The process of constructing the bomb was a complex one. It involved SA altering the TATP from a relatively safe state to one that was highly unstable. It involved integrating that now unstable explosive into a device that SA was able to detonate. Again, for obvious reasons, I am not going to detail those stages, but I am satisfied that this was not something SA would have been able to do based on a recollection of a video or even following along while he viewed it.
