Tyson was convicted of felony cocaine possession and misdemeanor DUI in Arizona in 2007. He was placed on 3 years probation. One of the conditions -- Tyson can't violate any laws.
If Arizona prosecutors believe Tyson crossed the legal line yesterday, they could attempt to violate his probation and he could face jail time.
A probation official tells TMZ if charges are filed against Tyson in L.A., that could trigger a probation violation. The official says worst case scenario for Tyson -- 2 1/2 years in State prison.
