Detectives investigating the serious attempted assault of a police sergeant in Hackney and a robbery continue to appeal for information and witnesses.
The police sergeant was on patrol in Stoke Newington Hight Street near the junction with Tyson Street, N16 at 17:41hrs on Wednesday, 11 January, when she came across a knifepoint robbery in progress.
Despite being alone, the female uniformed sergeant bravely pursued the male suspect.
When she caught up with him, he produced a knife and swung it violently towards her.
Using her officer safety training, the officer managed to step out of the force of the attacker and detained the 18-year-old man.
It was originally thought that the sergeant had been punched in the arm while detaining the suspect but upon investigation it appears that the officer was stabbed in her 'MetVest' which prevented her from receiving a stab wound.
The man resisted arrest but was subdued due to her efforts and help from passing members of the public. The officer did not require hospital treatment but did suffer swelling to her arm.
A mobile phone, stolen from the robbery victim was found in the suspect's possession. A knife has also been recovered.
The man was subsequently arrested and taken to an east London police station.
He has since been charged with attempted grievous bodily harm with intent (GBH) against the officer, possession of an offensive weapon and robbery. He will appear in custody at Thames Magistrate's Court on Friday, 13 January.
The victim of the robbery was shocked but unharmed.
Detective Inspector Paul Ridley, from Hackney CID is leading the investigation. He said: "There were several members of the public on Stoke Newington High Street that were present during the incident but have not yet been traced. It is vital that they come forward as the information they hold could assist us further with our investigation.
"The officer demonstrated a tremendous amount of bravery and courage to detain the man and I would also like to take the opportunity to thank the passing members of the public who came to assist the officer."
Any witnesses or anyone with any information is asked to contact detectives at Hackney CID on 101 or via Twitter @MetCC
