Power tools have been banned at car boot sales in Hounslow following a fight involving weapons that left five people in hospital .
One man was stabbed and another suffered a broken leg during a mass brawl in Hounslow Heath, close to the car boot sale, on Sunday, February 28.
Extra police officers have been on patrol for subsequent car boot sales at the site in Staines Road, Hounslow.
Inspector Jonathan Shard, of Hounslow Police, said officers had been working with the organisers to prevent future incidents.
He told getwestlondon organisers had agreed to prohibit the sale of power tools, which Insp Shard said had been the source of previous trouble.
Two people due in court over mass brawl
"Power tools are no longer accepted for sale at any of the car boot sales, as they were the driver for the attendance of the groups involved in the fight," he said.
"The managers of the car boot sales have agreed to a ban, which is advertised at the entrance to the site."
There is no suggestion any power tools were used as weapons during the fight last month.
Charles McDonagh, of Manor Waye, Uxbridge, and a 17-year-old boy, who cannot be named for legal reasons, have both been charged with violent disorder in connection with the brawl.
They are both due to appear at Feltham Magistrates' Court on Thursday (March 31).
Three men, aged 26-39, were also arrested and bailed in connection with the incident.
