The 67-year-old father of a family found living in isolation in a cellar in the Netherlands has been detained, police say.
He is accused of false imprisonment, abuse and money laundering, police from Assen, in the eastern province of Drenthe, said on Thursday.
"We detained the father," a police spokeswoman confirmed.
Many details are still unknown, but there were indications on Thursday that the father was a member of a cult.
A spokesman from the Unification Church, known colloquially as the Moonies, said he had been a member at some stage.
It comes after a 58-year-old man from Austria was taken into custody the previous day.
A judge decided the man, identified as Josef B, should stay in custody on Thursday.
Josef B was renting the farm in the village of Ruinerwold, where the family - a father and his six grown-up children - were found earlier in the week.
The family was discovered in a cellar at the farm after one of the sons sought help in a nearby pub.
They are thought to have lived there for nine years in isolation from the outside world.
