Will Wilson, aged 79, whose home in Rogers Close backs onto the land, said: "It's absolutely horrendous. I can't understand that we apply the litter law to people who drop cigarette ends but when we get these people leaving a horrible mess like this no one can take any action or doesn't bother taking action.
"It is indescribable really what has happened. When they arrived last week I said the mess when they left would wreak havoc and it's done exactly that.
"It's a beautiful area, kids play on there and people take their dogs for a walk and people are unhappy when they see it turned into an absolute mess and used a toilet."
Another resident, who asked not to be named, added: "We've been scared to leave our house for the past week, these people have no morals whatsoever.
"How they've left the park in that way is disgusting."
Another resident, who did want to be named, said: "Tell me how it's fair that residents could be potentially fined for allowing their dogs to dirt in the park but the travellers themselves are leaving human faeces for us to clean up, where's the justice?
"What have the police done in this situation? I haven't seen them at all over the last week."Either the law applies to everyone, or it doesn't...
