Armed police were in Borehamwood on Saturday after reports of a moped rider holding knife.

Officers rushed to the scene in the Aycliffe Road area of the town shortly after 5.30pm on Saturday and were joined by a police helicopter to search for the moped.

Hertfordshire Constabulary says it received a report of a "moped chasing a vehicle along Aycliffe Road" and the moped rider "appeared to be holding a knife".

In response, a number of units were sent to the area but following a search neither the moped or vehicle reportedly being chased were traced.

Enquiries are continuing.
