A convicted rapist identified by his GPS bracelet was arrested on Tuesday for allegedly attacking a woman in a South End park just months after serving a lengthy prison sentence for a nearly identical assault nine years ago, authorities said.

Eduardo Rodriguez, 31, was arrested on Massachusetts Avenue at 3:30 p.m., just blocks from where he allegedly accosted and threatened with a knife a woman walking Monday morning at 1 a.m. on Greenwich Park and Claremont Street. He allegedly forced the woman to walk more than a quarter-mile to Carter Playground, where he is accused of assaulting her.

“That shouldn’t happen in our city, but I’m glad we were able to get him very quickly,’’ said Boston Police Commissioner William B. Evans at a press conference at Boston Police Headquarters.

Rodriguez will be arraigned Wednesday in Roxbury Municipal Court on charges of aggravated rape, aggravated kidnapping, indecent assault and battery, intimidation of a witness, and armed robbery, police said.

Police knew very quickly that they were looking for ­Rodriguez, as his GPS bracelet placed him in the area at the time of the alleged rape, Evans said.

But Rodriguez allegedly cut off the bracelet afterward, and investigators began searching for him in the South End and at past addresses. He was ultimately arrested by an undercover officer who walked up to him on the street and grabbed him, officials said.

Evans praised the victim, saying her identification of her alleged rapist was crucial to helping police apprehend him.

“Due to her bravery, and her making a positive identification, we were able to lock this individual up,’’ Evans said. “This is a dangerous individual who committed an atrocious act.’’

The allegations closely mirrorthe rape Rodriguez was convicted of committing in Boston in February 2007. In that case, court records show he accosted an 18-year-old high school senior walking to school and told her he had a knife in his pocket.

He threatened to kill her if she tried to run or scream, and led her into a stairwell in a building on Tremont Street, where he raped her. He allegedly stole her money, cellphone, and jewelry, though a jury acquitted him of armed robbery, according to court documents.

Rodriguez was convicted of rape in 2008 and sentenced to 8 to 10 years in state prison, according to Jake Wark, spokesman for Suffolk District Attorney Daniel F. Conley.

Monday’s attack left women who live and walk through the garden-lined streets where it unfolded uneasy about the brazen violence.

“It makes me very nervous,’’ said Nicole Monroe, who works in the area and walked on her lunch break past the park where the alleged assault occurred. “It’s a little scary — and bold.’’

Greenwich Park and Claremont Street are quiet, residents said, with brick sidewalks and well-tended gardens. Flowers bloom around a sign for a “butterfly meadow,’’ and children zip past on bicycles. On Tuesday afternoon, people walked dogs and nannies pushed babies in strollers between playgrounds, basketball courts, and a tennis court.

Police did not say the route Rodriguez forced the woman to walk, but there is a winding pathway that crosses Massachusetts Avenue, avoids busy main streets, and leads to ­Carter Playground. At night, residents said, the section of pathway close to Carter Playground is dark and can be dangerous.

“I’ve lived in cities all my life,’’ said Barbara Wennerholm, who lives near Greenwich Park and was out walking her dog, Merlin. “It’s ingrained to look over my shoulder.When I walk into my house, I look over my shoulder to make sure nobody’s behind me.’’

The assault, she said, made her nervous for her teenage children, a boy and a girl, who she said think they’re invincible. She has warned them to be careful, she said.

Northeastern University theater major Eva Friedman, 21, said she is often at rehearsals late into the evening and walks through the area by herself. She has always felt fairly safe, she said, although she is careful not to wear her headphones and to stay aware of her surroundings. Like many women in the area, Friedman lamented the fact that so much of the responsibility falls on women to protect themselves.

“Talking to my guy friends, it’s not something they have to worry about,’’ she said.
