This story started in 2017, when three Russian daughters of the Lisovs were abducted by the Swedish CPS and were placed into a care of a culturally foreign family. The father managed to rescue his daughters in April 2019 (two years later!) and was on the way back to Russia through Poland, when the Swedish authorities demanded their extradiction.

Then the situation hang in balance. Back then the Polish court stood firm against the Swedish pressure: Love & justice: Russian family reunited by Polish court decision after fleeing Sweden
And now this case has finally come to a happy ending with the family back home in safety.
