A children's play area was left covered in mud and grass churned up by off-road bikers.
The incident is just the latest plaguing a suburb of Swansea, which witnessed grassy areas outside residential flats torn up by motorcyclists just before Christmas.
The latest incident in Hollett Road, Treboeth, saw play equipment splattered with mud and deep grooves criss-crossing the grass sometime on Saturday afternoon or evening, January 29.

Local resident Ben Davies said: "All I really want to know is why spoil things for the young ones? They have very few places to play outside and make friends."
He added: "They are always on the common, why start coming into the community and cause so much damage? It makes you so angry. Perhaps it's time to put some sort of fencing around all small parks".
In December, around ten bikers were caught on camera as they descended on the green areas next to flats off Heol Gwyrosydd in Penlan.
They were seen performing doughnuts and leaving muddy patches in the grass and were confronted by a grandmother waiting at a bus stop with her two young grandchildren.
Mynyddbach councillor Mike Lewis said: "Myself and the other ward councillors paid for this play area to be installed under two years ago, and there is extensive damage to the grassed areas but there is one piece of equipment which has been splattered with mud by these mindless idiots.
"We continue to be plagued by a group of seven or eight of these off-road bikers right across our, and neighbouring wards, especially over the weekends.
"They are not registered, have no plates, no tax and no insurance, and all seem to have straight through exhaust systems, which causes no end of resident complaints about the excessive noise they are producing.
"As local councillors we continue to try to put measures in place to frustrate these rogue riders, including fencing off ways of entry, putting in bike barriers and updating the local PCSOs to the latest areas that have been targeted by this gang of indiscriminate, thoughtless bike riders.
"From a public safety perspective, as local councillors we will look to have this area fenced off as soon as is possible, to avert a repeat of this incident and to ensure the future safety of our younger residents."
