BOSTON -- Police said they arrested and charged a Lowell man Thursday night after getting a call for help concerning a pregnant woman assaulted on Powell Street.

Officers said they arrived at 110 Powell St. about 9:45 p.m. to find a 28-year-old pregnant female lying on the bathroom floor of the apartment.

The victim was barely conscious and had visible injuries over her body consistent with blunt trauma, police said, and they could not determine how many months pregnant she was.

The victim was taken via medical helicopter to Brigham and Women’s Hospital in Boston where she was expected to survive.

The male suspect, Seap Sa, 35, of Lowell, was found hiding inside the apartment and was arrested and charged with domestic assault and battery by means of a dangerous weapon -- a wooden club -- and assault and battery on a pregnant person, police said.

Two other individuals inside the apartment were also arrested for interfering with the EMT’s providing emergency medical treatment to the victim, police said.

The case is under investigation.
