Authorities have arrested a suspect this weekend in connection with human remains found inside a duffel bag in Cambridge, according to the Middlesex District Attorney’s office.

The remains were found Saturday. The suspect is scheduled to be arraigned in Cambridge District Court on Monday, at which time the defendant’s name will be released. There, the suspect will face charges of accessory after the fact to assault and battery, causing serious bodily injury and improper disposal of a body.

The remains have been identified, but the victim’s name is being withheld as police look for the next of kin.

The investigation, said Middlesex District Attorney Marian Ryan, continues to be active as Cambridge detectives and State Police are continuing to gather information to “determine the circumstances which led to the discovery.”

Someone reported a suspicious item at Loughery Way, a pedestrian walkway near 225 Binney and 6th Streets in Cambridge Saturday morning. There, police found human remains in a duffel bag. Surveillance video led police inside a building, where body parts were also found. That video will not be released until the case is resolved, according to the DA.

“We’re confident that this was not a random act and there is no threat to the public’s safety as a suspect has been taken into custody,” said Cambridge Police Commissioner Robert Haas. “To provide additional assurance and peace of mind, our officers plan on going door-to-door to speak directly with any neighboring residents to address any questions or concerns they may have.”

Haas is encouraging anyone who has any information regarding the incident to call Cambridge Police at 617-349-3300.
