A 31-year-old Dorchester man arrested for raping a woman at a South End park was ordered held on $500,000 bail at his arraignment in court Wednesday.

Eduardo Rodriguez was charged with aggravated rape, indecent assault and battery, armed robbery, intimidation of a witness and aggravated kidnapping, officials say. 

Rodriguez was also ordered to submit to GPS monitoring, remain under home confinement, and have no contact with the victim in the event he is released on bail. 

The incident occurred around 1 a.m. on Monday, according to police, when a woman walking near Greenwich Park and Claremont Street was approached by Rodriguez, who told her that he had a knife. He then forced her to walk to Carter Playground and sexually assaulted her, officials said. 

He also stole about $250 from the victim's wallet before fleeing, Assistant District Attorney Elizabeth Riley told the court. 

Boston Police Special Investigations Unit found Rodriguez Tuesday around Mass. Ave. Rodriguez is currently on probation as part of his sentence on a prior sexual assault conviction, officials said, and allegedly cut off his court-ordered GPS monitor after the Monday attack.

That GPS unit showed Rodriguez travelling the exact path as the described attacker at the time of the assault.

Rodriguez was convicted in 2008 of aggravated rape, kidnapping and indecent asault and battery and was sentenced to eight to 10 years in state prison, followed by five years of probation, which began in December, prosecutors said. 

"I applaud the courage and strength of the survivor in this incident," Boston Police Commissioner Bill Evans said in a statement. "She showed incredible bravery. I am also grateful to my detectives for their hard work and commitment in identifying and arresting this violent felon and removing him from the streets of this city." 

Rodriguez is due back in court September 23.
