Aapo Halme has become Barnsley’s second centre-back signing in as many days.
The 21-year-old from Finland has joined on a three-year contract, with the Reds having an option for a further year.
Halme joins for an undisclosed fee from Barnsley’s Yorkshire rivals Leeds United, for whom he made one Championship start and came off the bench on three other occasions.
Halme – who signed for Leeds from HJK Helsinki in January last year – follows the arrival of fellow centre-back Toby Sibbick yesterday evening from AFC Wimbledon.
They join Dane Mads Anderson as the Reds’ central defenders following the departure of promotion heroes Liam Lindsay and Ethan Pinnock.
