The Brazilian had been suspended from first-team training since Monday for allegedly sending racist messages on his social media account after being provoked by a comment.
Writing on social media, the club said its Disciplinary Committee completed its investigation and internal proceedings in a fair and objective manner, during which Mesquita had the opportunity to state his case.
The club added that it maintains a strict zero-tolerance policy against racism and improper conduct.
The 19-year-old midfielder made two appearances for Tai Po since joining the club this summer.
