The order will be in place between 6pm on Friday 23 September and 6pm on Sunday 25 September, following reports of anti-social behaviour (ASB) in the town.
A dispersal order covering parts of Caldicot will come into effect at 6pm on Friday 23 September following several reports of anti-social behaviour.
The order will remain in place until 6pm on Sunday 25 September, covering Caldicot Castle, the town centre and residential streets nearby.
The areas covered by the order includes Newport Road, Sandy Lane, Mill Lane, Chepstow Road and the surrounding roads as shown on the below map.
Sergeant Lee Smith-Stephens said:
"Anti-social behaviour can have a negative impact on the quality of life of our communities and it won’t be tolerated in Gwent.
"Our officers are committed to protecting our communities and will take action against anyone intent on causing harm or disorder.
“If you have any concerns about anti-social behaviour, and see us on our patrols, please do stop to talk to us.
"Alternatively, you can report your concerns by calling 101, or by sending us a direct message via Facebook or Twitter.”
Dispersal orders give officers extra powers to direct groups to leave an area if they are involved in ASB or disorder, if members of the public are being harassed, alarmed or distressed or if officers think their behaviour may lead to ASB.
If they return to that area after being moved on, they face being arrested.
