Massachusetts State Police officers were dispatched to the scene of a multiple vehicle collision just before 9 p.m. Sunday on I-93 North. A second collision, shortly afterward, involved a Tewksbury Fire Department vehicle that had also responded to the crash.

The first crash, involving six vehicles, was reported at 8:46 p.m. and occurred about one mile south of Dascomb Road in Wilmington. According to State Police, two people were injured in the crash and both were transported to Lawrence General Hospital. One victim was identified as a 47-year-old female from Derry, NH and the other, a 53-year-old female from Lawrence. A State Police spokesman said both have  non-life threatening injuries.

Tewskbury rescue crews responded to the initial accident and one TFD vehicle, a Ford Explorer command vehicle, was struck by an alleged drunk driver at 9:32 p.m.

According to State Police, Cisar Bargas-Lopez, 24 of Chelsea, struck a the Explorer while operating a 2002 Dodge Carvan.  Cisar-Bargas was uninjured in the crash. He was arrested and charged with OUI Liquor,  having an open container of alcohol in a motor vehicle, unlicensed operation of a motor vehicle, marked lanes violation and a breakdown lane violation.  Additional charges may follow, said the spokesman, as the crash remains under investigation.

According to Tewksbury Fire Chief Mike Hazel, no Tewksbury Fire personnel were injured in the incident.

The case remains under investigation by troopers from Troop A and the Massachusetts State Police Collision Analysis and Reconstruction Section.
