Police are appealing for witnesses after an off-duty officer trying to intervene in a robbery was stabbed in an “absolutely appalling” attack in a busy shopping area.

Officers were called to the scene outside Luton Point shopping center on George Street at around 1.10pm yesterday (Saturday).

Two men are believed to have robbed a victim of his moped while brandishing a large knife or machete.

An off-duty Metropolitan Police officer attempted to thwart the robbery and was attacked before the criminals fled the scene, one on his moped and the other on the victim’s stolen moped.

Bedfordshire Police said the brave officer was taken to hospital where he was treated for injuries which are not considered life-threatening or life-changing.

Acting Police Chief Dan Vajzovic said: “The off-duty officer’s bravery is to be commended as, by putting himself in danger, he undoubtedly helped prevent further harm to the public. Rampant violence of this level is absolutely atrocious and has no place on the streets of our county.

“Thankfully, the officer is expected to make a full recovery, although this story could have been very different. I speak on behalf of the force and the general public to thank you for your bravery and selflessness in the line of duty. “His actions were nothing short of heroic.”

Bedfordshire Police and Crime Commissioner John Tizard said: “This is one of many examples of police officers putting themselves at risk in the public interest and to protect members of the public. Selfless interventions like this and a Effective policing are essential to making Bedfordshire’s streets safer.

“Even when off duty, this Met officer was ready to put himself in harm’s way to protect others. On behalf of the people of Bedfordshire, I thank him for his brave action and wish him all the best for a speedy recovery.”

Officers are asking anyone with information about the incident to come forward.

The men are described as being in their early 20s. One was wearing a black jacket and pants, the other was wearing a dark-colored jacket and gray sweatpants with a white stripe down the side.

Detective Inspector Jon Stow of Luton CID said: “This brazen attack took place in the middle of a busy area and must have been extremely terrifying for everyone who witnessed it.

“We believe the victim of the original bicycle theft left the scene, so we are especially interested in identifying him. We would also like to speak to anyone who was in the area at the time or who knows anything about this crime.

“We are dedicating resources to this investigation to locate those responsible. “We will also maintain a high visibility presence in Luton town center following this distressing incident and would welcome any residents to come and speak to us if they have concerns or information to share.”
