Prosecutors in Los Angeles are revealing for the primary time Smokey Robinson was investigated for an alleged sexual assault again in 2015 … however the probe didn’t end in felony costs.

The L.A. County District Legal professional’s Workplace tells TMZ … they found that in 2015 the D.A.’s workplace was offered with a sexual assault allegation towards Smokey, and that the case was kicked as much as prosecutors by the Los Angeles County Sheriff’s Division.

The D.A. says prosecutors in the end determined to not cost Smokey with against the law because of a scarcity of proof.

Our sources say the alleged sufferer from the 2015 sexual assault case is NOT one of many 4 nameless ladies who not too long ago sued Smokey for sexual battery, assault, false imprisonment and gender violence.

Three of the 4 ladies from the brand new lawsuit filed police experiences towards Smokey, and he is now the topic of a brand new LASD investigation.

Smokey’s denied the brand new claims, known as them a shakedown, and has filed a counter swimsuit.

Robinson’s lawyer Christopher Frost tells TMZ … “We’re happy that this assertion has been launched during which the LA District Legal professional has confirmed there was no foundation to file costs a decade in the past.”
