"Rhythm of the Night" singer El DeBarge is in the clear after he was arrested for drug possession this week -- because the L.A. County D.A. has declined to file charges.
According to official D.A. documents, the case was rejected due to insufficient evidence.
TMZ broke the story ... DeBarge was arrested on Tuesday for felony possession of narcotics with intent to sell -- the singer's third drug arrest since 2001.
According to the docs, police officers noticed DeBarge and another man speaking on the street -- and for some reason, decided to search them ... without giving a reason why.
After searching them and coming up with nothing -- cops claim they perused the surrounding area ... and found a baggie of rock cocaine hidden under a nearby car.
The other man insisted he was there to buy the rock from DeBarge -- but DeBarge denied the accusation ... and the D.A. decided there wasn't enough evidence to make the charge stick.
