PRINCETON - A man accused of breaking into a Birch Avenue home and sexually assaulting a woman in her sleep Wednesday, also broke into another home on the same street weeks earlier, police said Friday.

Pedro Arias-Santiago, 26, of Princeton, was initially arrested just after midnight Wednesday after a 28-year-old woman said she woke up to find him sexually assaulting her in her sleep. She ran from the house and called police, who quickly arrested Arias-Santiago outside.

The news of the assault was widely published and on Thursday, another woman came forward.

The second woman - a 19-year-old from Illinois - told police she was staying at the home on Birch Avenue around 5 a.m. on June 14 when Arias-Santiago came in through an unlocked door. She heard Arias-Santiago inside and confronted him, police said. Arias-Santiago fled the house but the woman did not file a report until this week.

She was not sexually assaulted in the burglary, police said.

There are several similarities between the two incidents - they both occurred on the 200 block of Birch Avenue and both times police believe Arias-Santiago entered the houses through an unlocked door. Both women told police they did not know Arias-Santiago before the burglaries.

Police don't believe there's a connection between the two women.

Arias-Santiago, originally from Guatemala, is in the country illegally, police have said. He lives on Leigh Avenue in Princeton and federal immigration authorities were notified of his arrest.

He is being held at Mercer County Correctional Center on a $200,000 bail. His bail hearing is scheduled for Wednesday morning.
