The controversial times at public swimming pools in Helsinki reserved for Muslim women are open to members of all nationalities.
Teemu Raatikainen, the head of the Jakomäki public pool, says that Finns have also come to the pool during Muslims-only hours.
He notes that it is not possible to check up on a customer's religious affiliation.
"We have not asked about it. We have trusted that customers know what times they are coming to."
