Shortly before midnight, uniformed officers performed a routine vehicle stop in Coopers Lane junction with Leyton High Road.
The van failed to stop and was chased by police.
Once they caught the vehicle, they got out of the car to talk to a male driver who is believed to be in his 50s.
He repeatedly stabbed one of the officers with a machete, cutting the side of his head and causing injuries around his body.
Fortunately, the officer was able to draw his taser and defend himself from further harm.
Another officer at the scene then detained the attacker and arrested him on suspicion of GBH.
Detective Chief Superintendent, Richard Tucker, says the officer “will recover” after visiting him in hospital.
The patrol officer is due to have an operation on his hand at 10am today. The cut to his head required stitching.
He has served for ten years and is described as having a “great sense of humour.”
Police have footage of the incident from a body worn camera and are performing background checks on the attacker.
“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,” said Inspector Julia James.
“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.”
Police are not looking for anyone else in relation to the incident and there are no other reported injuries.
A crime scene remains in place. At this stage, there is nothing to suggest this incident is terrorist related.Tags: Waltham Forest, Leyton
