Police arrested Marvin Castellanos, whom they confirmed is an illegal alien, on Monday, after he allegedly dragged a Missouri woman into an alley and tried to rape her at knifepoint.

The victim heard footsteps behind her while she was walking down the street and talking on the phone. Little did she know she was being stalked by an illegal alien. Castellanos allegedly struck, shoving her against a wall, covering her mouth, and holding a knife to her throat.

The terrified victim told police that Castellanos began to drag her into an alley when she began to scream.

“Don’t look at my face,” Castellanos said before punching her.

When she told him not to rob her, he replied: “All I want is sex.”

One witness on a bike saw Castellanos attempting to rape his victim but kept on riding to report the crime to police. Another witness saw the half-naked Castellanos pinning the woman against the alley’s wall and shouted: “What are you doing?”

Police say Castellanos then fled to a nearby bar. He claimed he had been there all night out of fear of being deported, the News-Leader reports.

Prosecutors asked for $100,000 bond:

Defendant held a knife to victim’s throat, pushed her against a wall and pulled her shorts down approximately six inches. Defendant punched the victim on the left side of her face. This defendant is clearly a threat to the community and this victim in particular. Defendant is also a flight risk; defendant told officers that he has been deported prior to this incident. Defendant stated that he was allowed to come back into the country for a month to take care of child support issues.
