A Lowell man allegedly raped a woman in Bay Village and attempted to rape another woman he randomly met in the Theater District last Saturday, according to court records.

Solomon Wambui, 25, was arraigned Monday in Boston Municipal Court, where he was ordered held without bail under the state’s dangerousness law. He has pleaded not guilty to charges of rape and assault with intent to rape, records show.

Around 4:30 a.m., a 26-year-old woman was walking home in Bay Village after working late, according to court records. The woman was talking to her mother on the phone when Wambui allegedly came up behind her on Cortes Street.

“Can you leave?” the woman asked Wambui, according to court records. “Can I have a personal space?”

Wambui allegedly responded by insisting that the woman “come with me. I can help you. I can bring you home,” prosecutors said in court filings.

At that point, Wambui allegedly grabbed the woman “by the front of the neck and then from behind and dragged her to the ground” and raped her, prosecutors said.

“The entire assault and rape of the first woman was caught on video,” prosecutors said.

As Wambui ran down Arlington Street, the woman recorded him on her cell phone, called 911 and gave police his description. Officers began canvassing the area and saw a man matching the suspect’s description walk out of Eliot Norton Park around 5:15 a.m., prosecutors said.

A 47-year-old woman walking nearby told police the man sexually assaulted her, prosecutors said.

She later told police she was walking on Charles Street South when a man started following her.

“She picked up her pace and then he did as well,” prosecutors said.

Wambui allegedly grabbed the woman and put his hand over her mouth, causing her to breathe because of her asthma, prosecutors said.

Wambui allegedly forced her into the grassy section of the park and assaulted her, prosecutors said.

“She was crying. She tried to get away from him by twisting and contorting her body. The victim tried to scream as much as possible, but with the hand covering her mouth, it was difficult,” prosecutors said.

The woman was able to get Wambui to stop and walk out of the park with her “to see if she could get away from him,” prosecutors said.

Police searching for the man who raped the woman on Cortes Street saw Wambui and noticed his zipper was open and he was bleeding from a scratch, prosecutors said. Officers arrested him in connection with both attacks, prosecutors said.

“The nature and circumstances of these crimes can only be described as violent, cruel and absolutely heinous,” prosecutors said. “The only reason he was discovered and ultimately arrested was because he assaulted another victim close in time and close to assaulting the first victim.”

In court papers, prosecutors said Wambui had no prior domestic violence convictions and was not on probation for any recent convictions.

His attorney was not immediately available Friday.

His arrest was first reported by the Boston Herald.

Wambui is due back in court on November 22.
