A Labour MP has said vandals do not “intimidate” her after the window and door of her office were smashed.

Stella Creasy, who has represented Walthamstow since 2010, and is running in the constituency in the upcoming general election, posted images of the damage on social media.

Police said that the office in Orford Road was targeted between 3.10am and 3.30am on Sunday (June 22).

Creasy wrote on X: “Message to whoever attacked my office last night. You don’t intimidate me and you don’t belong in the political process.

“Same as those circulating malicious and false leaflets. Police already on this to find you – will press for the strongest penalties for such an anti-democratic attack and I know Walthamstow won’t be cowed or influenced by your violence either.”

Detective Superintendent Dion Brown said: “It is entirely unacceptable for the office of one of London’s prospective parliamentary candidates to be targeted in this way.

“An urgent investigation is under way, and officers have attended the scene and are already following up active lines of enquiry, which will include full analysis of available CCTV footage.”

Scotland Yard also posted a CCTV image of a hooded man on social media.

A Labour spokesperson said: “We completely condemn any intimidation tactics towards candidates of any party. It is vital to our democracy that parliamentary candidates are able to campaign freely.”

Anyone with information is asked to call police on 101, quoting reference 2621/23jun.
