Are there suggestions that the first incident was a publicity stunt? Yes, the arrest does seem strange, not least because they took him to the Garda station rather than a psychiatric unit. Taking the children in the middle of the night seems especially odd, unless there was no other adult in the house. The children are now with their mother. Perhaps there's some history there that we aren't aware of but may have caused the Guards to be concerned for the children's safety. Best not to speculate. I expect the court will sort it out and if the Guards overstepped the mark, he can take an action against them for wrongful arrest. They need to find out the identity of the person who made the complaint, especially if she pretended to be his deceased mother.
