Anthony McGrath, 57, who previously made allegations against Greater Manchester mayor Andy Burnham, is on trial as prosecutors say he threatened to bomb Greater Manchester Police headquarters. According to court reporting, the threats were posted on the social media platform X. Prosecutors say the messages were directed at police and referenced bombing the force’s headquarters in Manchester. The case focuses on the existence and content of the posted threats and their impact on public safety and policing. Burnham’s alleged role is part of the broader context of McGrath’s public accusations, but the court proceedings described in the coverage concentrate on the reported threat to bomb police facilities. The accounts do not indicate any successful bombing attempt. The reporting reflects that the court hears evidence about what McGrath posted, when he posted it, and how police responded to the information. The defendant is described in relation to both the earlier accusations and the later threat, which prosecutors argue constitutes a serious offence. The trial outcome is not stated in the provided summaries.
