During the early hours of Saturday (4 March), a 16-year-old boy from Hemel Hempstead was arrested on suspicion of assault causing grievous bodily harm (GBH) and violent disorder.

However, the suspect has since been released on bail as enquiries into the incident continue.

Detective Sergeant Paul Burton, from the Dacorum Local Crime Unit, said: “I know this incident has understandably caused a great deal of concern among the local community and I would like to reassure people we are doing all we can to investigate. It is believed that those involved are known to each other.

“As an arrest has been made, it is imperative that the case is allowed to proceed unimpeded, and we would ask people to please refrain from commenting or speculating on social media.

“We’re also still appealing for any witnesses to come forward. If you have information which may assist our ongoing enquiries, please get in touch. Thank you.”

Anyone with information is asked to please contact DS Burton via email.
