Armed police were deployed “as a precaution” after a group of men were seen running towards a train station with one person allegedly brandishing a knife.

Hertfordshire Constabulary received reports of four men seen running towards Watford Junction from the direction of Woodford Road at 4.40pm yesterday – and one man may have been carrying a bladed weapon.

Armed units responded and a search of the area was made.

Police said no suspects were found and enquiries continue.
