UXBRIDGE - A Woonsocket, R.I. police officer was held on $100,000 cash bail Thursday after allegedly breaking into an ex-girlfriend's home, hiding in a closet, and then assaulting her when she returned from a bar.

Enrique Sosa, 41, of 77 Fulton St., Woonsocket, was arrested and charged early Thursday morning with nighttime felony breaking and entering, assault and battery on a family/ household member, and assault with a dangerous weapon.

Uxbridge police reported responding around 2 a.m. Thursday to an address on the 700 block of Aldrich Street where a caller said a bleeding woman was on her porch asking for help.

Police arrived at the home to find the victim “cowering in fear in the lower left corner of the front door frame” and Mr. Sosa standing about 20 feet from the front of the house trying to speak with the woman, Uxbridge Police Officer John Larrabee wrote in a report.

“He immediately placed his hands behind his back and said, ‘just arrest me now,’” Officer Larrabee reported. “‘I’m a cop guys,” the man continued. “‘I’m a Woonsocket cop. I worked so hard to get where I am, and I (expletive) it all up, I know it.’”

Police said that Mr. Sosa had slurred speech, was unsteady on his feet, and that they smelled alcohol.

Police reported that the victim told officers she had come home from a bar when she heard a noise on the first floor. She told officers she grabbed a steak knife for protection then noticed her cats looking toward the foyer closet.

The victim told police that when she approached the closet, Mr. Sosa jumped out, took the knife from her and started yelling, asking why she was at the bar.

The victim told police she thought Mr. Sosa “was going to stab or kill her,” police reported.

The two allegedly began fighting over the knife, and Mr. Sosa allegedly began slashing at his wrists with it and then held it pointed at his chest.

During the scuffle, the victim was cut in the right hand and the blood prevented her from using her cellphone to call 911, police reported. The victim got back the knife and left for the Aldrich Street home for help. The victim told police she and Mr. Sosa had been dating on and off for five years and broke up again about a month earlier.

“She continued with, ‘no matter where I am he finds me,’” Officer Larrabee reported. The victim also told police that Mr. Sosa would threaten suicide whenever they broke up and kept a gun in his car, which police reported recovering.

Mr. Sosa reportedly told police that he was suspicious of the victim cheating on him so he drove by the bar and saw her car. He said he drove to her house and sat on her steps, entering the house to go to the bathroom, and was inside when she arrived, police reported.

Judge Gerald A. Lemire ordered Mr. Sosa held on $100,000 cash bail and a $1,000,000 surety at his arraignment Thursday in Uxbridge District Court.

Mr. Sosa is scheduled to return to court Friday for a mental health evaluation, according to court documents.

Woonsocket Police Chief Thomas F. Oates III said in a phone message Friday that Mr. Sosa has been suspended without pay.
