Hero Detective Dismissed Over Offensive WhatsApp Messages
A decorated police detective who was among the first responders to the 2017 London Bridge terror attack has been dismissed from the British Transport Police (BTP) for making derogatory jokes about travellers on WhatsApp. Detective Constable Mark Luker, an officer with over two decades of service, was found guilty of gross misconduct following a public hearing earlier this month.
London Bridge Response and Subsequent Fall from Grace
In June 2017, Detective Constable Luker rushed to the scene after three terrorists deliberately drove a van into pedestrians on London Bridge before fleeing to Borough Market and stabbing innocent bystanders. The attack resulted in eight fatalities and forty-eight injuries. Despite his heroic actions during this national crisis, Luker's career has now ended in disgrace due to his inappropriate communications.
The misconduct panel heard that Luker was a member of a WhatsApp group called 'Selbie Gumshoes' with other members of the Major Serious and Organised Crime (MSOC) team. In messages spanning from December 2024 to March of last year, he repeatedly used language that linked the Irish Traveller community to criminal activity.
Offensive Language and Cultural References
On December 31, 2024, during a conversation about a bottle of whiskey with a security tag still attached, Luker wrote: 'Was this a raffle on a certain kind of site? Lots of mobile type homes? Lots of "Dags"'. He then added: 'You are the MSOC pikey liaison'. The panel determined that 'dags' referenced a scene in the Guy Ritchie film Snatch where a Gypsy character's accent is mocked, making the term derogatory.
Further messages revealed additional offensive content. On March 17 last year, when another group member shared a video of a 'Paddy Day parade on Inishbofin' with the comment 'Just like a Disney World Parade. They know how to put on a show,' Luker replied: 'Off to find some scrap metal, lead roofing and cable'. The panel concluded this deliberately and discriminatorily linked the Gypsy, Roma and Traveller community to theft.
Defence and Panel Findings
During the hearing, Luker explained that humour was one of his coping mechanisms for dealing with the trauma of responding to the London Bridge attack. Concerning his use of the term 'pikey', he stated that he grew up in west London with many Irish travellers and considered it a word simply denoting a traveller. He expressed deep regret and immense sorrow, claiming he did not intend to use discriminatory language.
However, the misconduct panel found that as an experienced police officer accustomed to interacting with diverse communities, Luker probably knew his language was 'especially offensive' to minority groups. While accepting he is not 'inherently racist,' the panel ruled his messages constituted gross misconduct. They were described as 'deliberate messages, that clearly link the Irish Traveller community to acts of theft' and 'disrespectful' in nature.
Career Achievements Contrasted with Misconduct
The dismissal marks a dramatic fall for an officer previously recognised for exemplary service. In 2023, Luker was among those honoured at the annual British Transport Police Federation Awards of Excellence, which champions exceptional police work. He accepted an award on behalf of the MSOC Investigation Review team for their work on unsolved and undetected rape offences.
The panel's decision underscores the serious consequences of discriminatory language within police communications, even for officers with distinguished records. This case highlights ongoing challenges in ensuring appropriate conduct among law enforcement personnel, particularly in digital communications where humour can cross into offensive territory with significant professional repercussions.
