A police officer is being treated in hospital after being attacked with a machete.

The incident happened shortly after midnight on Thursday (August 8) at the junction between Coopers Lane and Leyton High Road, Leyton.

The driver, aged in his 50s, failed to stop for police and made off. The driver was followed briefly by police on ‘blues and twos’ and stopped a short while later.

Officers got out of the police car to speak to the driver.

But the driver attacked a uniformed police officer with a machete, repeatedly stabbing him before the officer managed to draw his taser and subdued the suspect and protect himself from further harm.

The suspect was then promptly arrested by the other officer in attendance.

The injured officer, aged 28, was taken to hospital by London Ambulance Service and remains in a critical but stable condition. His next of kin have been informed.

He is being treated for a wound to the side of his head, which requires stitches, and an injured hand from fending off the attacker.

Detective Chief Superintendent Richard Tucker, who described the attack as "frenzied and unprovoked", said the officer is "seriously injured, but he will make a recovery".

The driver was arrested at the scene on suspicion of GBH and taken to an east London police station for questioning. He did not require hospital treatment.

Police are not looking for anyone else in connection with this incident and there are no other reported injuries. Enquiries continue.

A cordon remains in place in the wake of the attack, police say there is nothing to suggest this incident is terrorist related.

Inspector Julia James from North East Command Unit said: “This was a sudden and brutal attack on a uniformed officer carrying out their duties. What began as a routine vehicle stop has transformed very quickly and unexpectedly into an unprovoked attack with a weapon.

“Our thoughts are with the injured officer and his family and we wish him a full recovery. I would like to commend his bravery and resilience especially as he managed to draw a taser, despite being repeatedly stabbed, to prevent the suspect harming anyone else and to protect himself from further injury.

“My colleagues came to work that evening to protect and serve the community. Events such as this highlight the courageous work that police do every day, sometimes having to confront violent and dangerous individuals, who are determined to do them harm.

“This incident highlights the very real risk that police officers can be confronted with on a daily basis and the courage and professionalism officers demonstrate when doing their job.

“I would urge any witnesses to the incident to contact police via 101 quoting CAD3/8August or Crimestoppers anonymously via 0800 555 111.”
