Police are appealing for witnesses and information following an attempted robbery in Harpenden.
The incident happened on Friday 8 November, at around 3.30pm, on Waveney Road.
The victim was walking home from school when he was approached by the suspect, who asked him to hand over his bag. The victim refused, and the suspect then punched him in the face. Whilst the victim was on the floor, the suspect allegedly withdrew a small knife from his pocket.
The victim managed to flee the scene, and a member of the public – who has not yet been identified – intervened.
Detective Constable Krisztina Gulyas, of the St Albans Local Crime Unit, said: “I’m aware that some time has passed since this incident took place, but we’re just making sure we have exhausted all lines of enquiry. Despite attempts, we have so far been unable to identify the member of the public who bravely stepped in. We’re hoping to identify them, as they may have vital information which could greatly assist our investigation.
“If you were in the area at the time and believe you may have witnessed the incident, or if you think you have information which could help with our enquiries, please get in contact.”
Anyone with information is asked to contact DC Gulyas directly via email at Krisztina.Gulyas@herts.pnn.police.uk.
