Police are working to resolve disruption on the #A127 near to the Halfway House and Warley after receiving reports shortly before 10am of the road being blocked and pony and trap racing taking place.
Two people have been arrested – one on suspicion of assaulting a police officer and one on suspicion of possession of an offensive weapon.
A notice under Section 35 of the Crime and Anti-Social Behaviour Act has been put in place for the whole of the A127 between the M25 and the Rettendon turn-off.
This will give officers the power to move on anyone causing anti-social behaviour.
The A127 is now open in both directions although the traffic flow may take some time return normal.
