Specialist Operations

Rejoining the Met in February 2005, Hayman left Norfolk to become the Metropolitan Police Service's Assistant Commissioner for Specialist Operations, a role which placed him in overall charge of counter-terrorism operations conducted by the now defunct Special Branch and the Anti-Terrorist Branch.

Six months after taking up the post as head of Specialist Operations, Hayman was the overall head of the investigation into the 7 July 2005 London bombings, the largest criminal investigation in British history. In the 2006 Queen's Birthday Honours he was appointed Commander of the Order of the British Empire for his handling of the investigation.

Hayman resigned from the Service on 4 December 2007, following allegations about expense claims and alleged improper conduct with a female member of the Independent Police Complaints Commission (IPCC) and a female sergeant.

Hayman, along with Commissioner Sir Ian Blair, was criticised by the press and the Independent Police Complaints Commission over the mistaken shooting dead of Jean Charles de Menezes at Stockwell Underground station on 22 July 2005.
