A 31-year-old Leicester man was arrested in Haverhill on an armed assault to murder warrant in connection to a death in Worcester that police said appeared “to be suspicious.”

Worcester police said they arrested Marcel Santos-Padgett at 4 Colombia Park on an arrest warrant “that resulted from the investigation into the death of a female at 383 Pleasant St.”

Police said they were dispatched to Angie’s Body Work Spa on Pleasant Street in Worcester just after 11:30 a.m. Thursday for a report of a woman “experiencing a possible medical issue.”

When officers arrived, a man brought them to an unconscious woman who was declared dead at the scene by emergency medical personnel, police said.

“The death appears to be suspicious,” the Worcester Police Department said in a statement.

Violence also marked Thanksgiving in the Greater Boston area, where one woman was shot and killed in Cambridge and two men were found stabbed in downtown Boston. A man was shot and killed in Boston Saturday morning and a woman was shot in Hyde Park Friday night.
