Six people have been arrested and weapons seized after violence on Southend seafront.
A section 60 dispersal order, which gives officers authority to exercise powers of stop and search, is in place after reports of violence around 7pm on Tuesday night.
Footage on social media appeared to show at least four people in black waving machetes near the Adventure Island theme park.
Southend councillor Daniel Cowan tweeted: “I’m urging calm and encouraging people to avoid Jubilee beach this evening as @EssexPoliceUK deal with a large influx of young people.
“It’s a developing situation that CCTV is monitoring and more police resources are en route to support the dispersal order that is in place.”
Exxex Police said the order will remain in place until 8pm on Wednesday.
