The REAL Reason Apollo Nida Went Back to Jail.

Last week Real Housewives of Atlanta ex-husband Apollo Nida was sent back to jail after violating his probation.

Now we know why...

Insiders tell Sandra Rose Apollo broke a rule regarding intimate relations at his halfway house in Philadelphia.

It is not clear if his intimate partner was his fiancée Sherien Almufti or a resident of the halfway house.

Apollo could now remain behind bars until his original release date of October 15, 2019.
