English-born of Ghanaian descent, Osei-Bonsu ended his stay with the Dons at the end of March.
The 18-year-old mutually parted ways with the League One outfit after ten-years – having started his football career in England with the Dons at the age of 8.
He was loaned out to then Evo-Stik League Premier side Corby Town on a `work experience` basis in January until the end of the season.
Bonsu is eligible to feature for either Ghana or England.
