Just looked him up on Wiki and found this:
"Born in
Bujumbura, the capital of Burundi, Berahino played football as a child with a ball of plastic bags tied up with laces. His father was killed in 1997 during the
Burundian Civil War. He travelled to England alone at the age of 10, fleeing the ongoing war to join his mother, brother and sisters who had already been granted asylum in
Newtown, Birmingham. He could not locate his family on arrival, and was put in a care home. After his mother Liliane was traced, immigration officials had to administer a DNA test to confirm their relationship."

That's a tough upbringing, but I'm glad for him that he gets to represent his birth country now.
