The attack
The attack occurred as concertgoers were leaving Manchester Arena on May 22, 2017. Twenty-two victims were killed and many more were injured. Salman Abedi, who carried out the attack, died at the scene.
This file does not reproduce graphic descriptions or technical information about the attack. The record is presented through the criminal case and the later statutory inquiry.
Hashem Abedi's prosecution
Prosecutors alleged that Hashem Abedi played an integral role in the planning and preparation of the attack, even though he was in Libya when the explosion occurred. In March 2020, a jury convicted him of 22 counts of murder, attempted murder and conspiracy to cause an explosion likely to endanger life.
In August 2020, the Old Bailey imposed 24 life sentences. The murder convictions carried a minimum term of 55 years before parole may be considered. The sentencing judge said Hashem and Salman were equally culpable for the deaths and injuries caused.
A later admission
Although Hashem denied involvement at trial, the Manchester Arena Inquiry later heard evidence that, during a prison interview in October 2020, he admitted playing a full and knowing part in the planning and preparation of the attack.
The public inquiry separated criminal guilt from institutional failures
The Manchester Arena Inquiry examined security arrangements, the emergency response, radicalisation and preventability. Its findings are not additional criminal convictions. They address what organisations and public bodies knew, how they responded and what changes were needed.
The inquiry published three major volumes, with the final volume on radicalisation and preventability released on March 2, 2023. The findings created an extensive institutional record without changing Hashem Abedi's 2020 murder convictions or 55-year minimum term.
Current legal position
Hashem Abedi remains imprisoned under the life sentence imposed for the Arena attack. Separate criminal allegations arising from later conduct in prison are legally distinct and do not alter the Manchester Arena convictions.
