A police chief has apologised after admitting phones were twice seized from the Manchester synagogue attacker months before the car and knife assault but they were not examined.
Jihad Al-Shamie, 35, was on bail for an alleged rape when he carried out the attack on Heaton Park Synagogue in Crumpsall on 2 October 2025, in which two Jewish men were killed.
His devices, which contained evidence of his extreme views, were seized after he was arrested in February and September but not analysed.
Greater Manchester Police Chief Constable Sir Stephen Watson said he was “deeply sorry”, conceding that “the information contained within these devices would have inspired further investigative action”.
Sir Stephen said the end of legal proceedings against Mohammad Bashir, who has been jailed for life with a minimum term of 17 years for plotting a separate attack with Al-Shamie, meant rules around sharing information about a live criminal case had been lifted.
He said: “In conducting an internal review, it became apparent that GMP had seized Al-Shamie’s mobile devices, at the point of each arrest.
“The significance of the data contents of these devices was substantial in respect of evidencing an extremist mindset.
“I am disappointed at the prospect of adding to the distress of all of those affected by the terrible events last October.
“For this, I am deeply sorry.”
