Tough break for Raymond Cruz -- the actor who brought fan-fav villain Tuco Salamanca to life -- 'cause cops hauled him in this morning on suspicion of misdemeanor battery.

A source familiar with the case tells TMZ ... Cruz was washing his car and asked the girl to move out of the way. When she didn't, she allegedly got sprayed and believed he did it on purpose.

The incident went down outside Cruz's home in the Silverlake area of Los Angeles.
