Travellers who have parked on a Northamptonshire cricket club will be issued a notice to leave say the county council.
Barby Cricket Club tweeted earlier this afternoon warning other not to "suffer the same" and keep sites well secured.
"Local clubs please be aware," the tweet states.
"Travellers have broken into our ground and parked on our pitch.
"Make sure you don’t suffer the same, make sure your site is well secured."
A spokesman for Northamptonshire County Council said: “The Countywide Traveller Unit is currently preparing paperwork to issue a notice for the encampment to vacate the site.”
