French authorities detain pogbas brother
I think there may be some confusion here. Paul Pogba is a French professional footballer who plays for Manchester United and the France national team. He has a younger brother named Mathias Pogba, who is also a footballer.
However, I couldn't find any recent news or reports about French authorities detaining Paul Pogba's brother. It's possible that you may be referring to a different person or incident.
If you could provide more context or clarify what you're referring to, I'd be happy to try and help you find more information.
