A former Uber driver accused of sexually assaulting a female passenger has been linked to a string of unsolved sexual assault cases in Boston dating back nearly a decade.
Alejandro Done, 46, of Boston, was arrested by Cambridge Police in December and charged with beating and raping a passenger after he presented himself as a driver for the ride-for-hire service.
Suffolk County District Attorney Dan Conley announced Tuesday that a DNA sample ordered in the Cambridge case as well as an "unmistakable pattern of conduct" has allegedly linked Done to five unsolved sexual assaults between 2006 and 2010 — two in South Boston and three along the Esplanade.
"They were all very violent, predatory, stalking-type of violent assaults," Conley said during a press conference on the Esplanade Tuesday.
Conley said it was possible Done could face charges in other cases that authorities believe follow a similar pattern.
Done, who has been held without bail since his December arrest, will likely be arraigned on the new charges later this week.
Correction: An earlier version of this story incorrectly reported the number of cases Alejandro Done was newly linked to. It's five cases, not four.
