Greater Manchester Police's (GMP) admissions have thrown a harsh spotlight on the critical lapse in their procedures leading up to the devastating attack on the Heaton Park synagogue, where one person was fatally shot and several others injured. The force has acknowledged that mobile phones seized from attacker Jihad al-Shamie during two previous arrests were not properly examined for crucial data before the assault.
The revelations have sparked widespread concern and calls for greater transparency within GMP's investigative processes. Chief Constable Sir Stephen Watson stated unequivocally that there was "little doubt" examining the devices would have triggered additional action, underlining the severity of the missed opportunity.
Shamie's attack on Yom Kippur in October 2025 occurred just two months after he and his accomplice Mohammad Bashir had been detained by police. It has since emerged that Shamie's mobile phones contained extremist content, which was not realised or examined during these previous arrests.
The IOPC has initiated a review into GMP's handling of intelligence and evidence in the lead-up to the attack, with Sir Stephen expressing regret for any additional distress caused to those affected. The chief constable noted that the timing of this apology coincides with Bashir receiving a life sentence with a minimum term of 17 years for his involvement in planning the terrorist act.
GMP's internal review has revealed that Shamie was arrested on two separate occasions – in February and September 2025 – but despite seizing his mobile devices, critical data stored on them went unexamined until after the devastating attack. The implications of this oversight are far-reaching, prompting renewed scrutiny of GMP's procedures.
The Independent Office for Police Conduct will now scrutinise GMP's actions in detail, assessing whether the missed opportunity was a result of individual errors or systemic failings within the force. The review aims to shed light on how such critical intelligence was overlooked and what steps can be taken to prevent similar lapses in the future.
