A Met Police sergeant from the South West Command Unit, which covers the boroughs of Kingston, Merton, Richmond, and Wandsworth, has been dismissed after assaulting a woman known to him.

Sergeant Chris Allonby, attached to the Met's South West Command Unit, was sacked following a misconduct hearing which concluded yesterday (Tuesday, 10 June).

Sgt Allonby was found to have assaulted his former partner in 2018, 2019, and 2021, all while off-duty.

The Met said a panel heard that Sgt Allonby was a verbally and emotionally abusive partner, displaying a pattern of unwanted behaviour towards his ex-partner, in addition to carrying out physical assaults.

Detective Chief Superintendent Christina Jessah, who leads policing in the area, said: "Sgt Chris Allonby exhibited consistently unacceptable and wholly inappropriate behaviour.

"It is right he faced disciplinary action and is no longer a part of the Metropolitan Police Service.

"We commend the bravery of his ex-partner, who spoke up and enabled us to take action."

The panel found the officer had breached the standards of professional behaviour relating to authority, respect and courtesy, and discreditable conduct – stating that "his actions amounted to gross misconduct."

Sgt Allonby will now be placed on the College of Policing's barred list, banning him from employment with any police force, local policing body, the Independent Office for Police Conduct, or His Majesty's Inspectorate of Constabulary and Fire & Rescue Services.
