Armed police and helicopter used following fight

Armed police and a helicopter were called in after a fight in Brighton, East Sussex, on Thursday evening, Sussex Police say.
Three men escaped from the scene in Bamford Close, in a car which was later dumped and set alight.
Police said they recovered "a bladed weapon" near the vehicle.
No arrests have been made.

Det Insp Duncan Lloyd said witnesses who called police at about 18:20 BST reported seeing three men driving away in the car, which was already badly damaged.
He said: "Other members of the public called in to report the car being driven in the city, before it was dumped in Whitehawk Road and set alight. We found a bladed weapon close-by.
"The public support has been tremendous in what was a dynamic situation and it has helped us build a picture of what happened and who may be involved.
"Our officers were supported by the National Police Air Service in a search of the area, and that search has concluded."
He said officers were now investigating.

Patrols in the area are being increased, a Sussex Police spokesperson says.
Anyone with any information is being urged to contact the force.
