Detectives are appealing for witnesses and information following a robbery in Hemel Hempstead.
The incident occurred in Gadebridge skate park, between 6.50pm and 7pm on Friday, May 13.
An 18-year-old man was in the park with his friends when he was approached by two unknown males who asked him to hand over his property.
When the victim refused, a scuffle ensued, and a knife was produced.
The victim subsequently handed over his black Nike man bag and the suspects left on foot towards the High Street.
No one was injured during the incident.
Detective Constable James Macpherson, from the Dacorum Local Crime Unit, said: “Thankfully the victim was not injured during the incident but has been left shaken by what happened. The park was busy at the time and I am therefore appealing for anyone who saw the incident, or who may have seen the suspects in the area to please get in touch.”
