Blackpill Lido shut as cooking oil poured into water
A lido has been closed after vandals poured cooking oil in it.
Swansea council said two large drums of oil were poured across Blackpill Lido overnight into Thursday - the lido was shut for several days last month because of a similar attack.
It said it was working with police who are looking at CCTV to identify the culprits.
Robert Francis-Davies, cabinet member for tourism, said: "It's unacceptable and it's unbelievable".
"We are in the height of the summer season and on the sunny days we've been having recently the Lido has been packed," he added.
The council said it could not risk damaging filter systems on the lido and would have to check filters before refilling the pool with fresh water.
Mr Francis-Davies added: "Clearing up the mess will take time but we will do all we can to get it back up and running as soon as possible."
The council tweeted to say the lido would stay closed on Friday and its staff were "working hard to get it up and running".
South Wales Police urged anyone with information to contact them.
