'100' caravans have been spotted in a field in Crayford, after travellers pitched up yesterday and more joined them today.
The field is near Maxim Road opposite Sainsbury's supermarket and the greyhound stadium.
A woman who lives nearby, who did not want to be named, said: "It started off yesterday with about 30 or 50 caravans, and today there are even more, I'd say about 100.
"You could here the generators going all night and there's a smell in the air - a burnt smell, the smell of burning."
A police spokesman said: "Police were made aware at 4.29pm on Tuesday August 26 that a number of vehicles and caravans had set up in a field off Maxine Road in Crayford.
"Officers attended the site and are working with the landowners to resolve the matter."
