Revellers in Kent who organise illegal raves over the summer months will "not be tolerated", police have warned.
Kent Police said they "will prosecute and seize the equipment of anyone found to be involved" in raves in the county.
The warning comes after officers said they found four men lying unconscious in the middle of a road after an event in Challock, near Ashford, in April.
A spokesman said they were believed to have overdosed on the class C drug ketamine and had since recovered.
'Unsafe and disruptive'
Assistant Chief Constable Andy Adams said: "We won't tolerate illegal raves which are a common problem across the south east.
"Whilst we will work with the organisers of licensed musical events, we will commit extra resources to prevent, disrupt and close down those who continue to flout the law and start unlicensed and illegal events in Kent."
He added: "Raves are unsafe and disruptive to our local communities with loud noise and property damage that greatly affect the quality of life of local residents.
"We will continue to take a hard line against the people who organise raves and will prosecute and seize the equipment of anyone found to be involved."
