A Brownsville man is behind bars facing aggravated sexual assault charges.

Police arrested 29 year old Ronald Fuentes Monday after a 21 year old woman claims he sexually assaulted her on Saturday night.

Fuentes worked as a mechanic at a local tire shop on south most boulevard. The victim took her car for service and later received a call from Fuentes asking her for a ride home.

Although she didn’t know the suspect well, she aided him and once they were at his residence he allegedly made sexual advances, restrained her, punched her several times and sexually assaulted her.

The victim escaped and called police. Fuentes was later arrested, charged accordingly and issued a 100 thousand dollar bond.
