The 16 people were taken to area hospitals by ambulances after a Black SUV crashed into the store, Plymouth County District Attorney Tim Cruz said during a press conference.
Mr Cruz said the driver was a man currently in the presence of police officers. He added that he was unable to say at this time if prosecutorial action will be taken.
Hingham Fire Chief Steve Murphy said that several people were pinned against the door at the back of the shop. He added that the structural integrity of the building is being evaluated but that there are no concerns at this time.
Mr Cruz said that several 911 calls came in from the Derby Street shops at around 10.45am.
“A dark-colored SUV appears, went through at a rate of speed undetermined, through a … glass window and struck multiple people,” Mr Cruz told reporters
“Sixteen people have been transported to hospitals,” he added. “There’s been one fatality.”
The page for the Derby Street location on Apple’s site states: “We’re sorry for the inconvenience while this store is closed. Until we can reopen again, please consider using our online services.”
Mr Cruz said employees were “visibly shaken and they’re assembling nearby”.
“This investigation is active and ongoing. We are very limited as to what we can say at this point,” he added.
“Fourteen of the victims were taken to South Shore Hospital and Weymouth and two victims [were] taken to Boston area hospitals,” Mr Cruz said.
The local outlet identified the car as a Toyota 4Runner.
Police called for a tow truck to remove the vehicle which is lodged in the back wall of the shop, trapping people inside.
Several ambulances from departments some distance away from Hingham have been brought to the scene, as well as a medical helicopter.
The crash took place at a shopping centre on Derby Street. A bus from the MBTA was put into use as triage.
As of 11.49am, the South Shore Hospital wasn’t taking on any further patients, police radio communications revealed, the local outlet reported.
The glass wall of the store had a large hole in it, footage from the scene shows.
Following the crash, several people were laying on the ground just outside the store as they were being taken care of by first responders.
“My wife is at Derby Street in Hingham, a black 4Runner drove full speed into the Apple store,” one man posted on Twitter. “She said there are a lot of injuries −my wife used a spare jacket as a tourniquet.”
“It sounded like an explosion,” one witness said, according to WCVB. “It was so loud.”
One person at the scene told the local TV station that the driver was bloody but alive when they were removed from the SUV by emergency workers.
“You’d have to really be picking up speed to end up in the storage area at the back side of the Apple store,” Frank O’Brien, who was shopping in the area at the time of the incident, told WCVB.
Lynne Goyuk told Boston 25 News that “It sounded like a bomb went off. We saw several people who should have sought medical attention, but they wouldn’t go over because they knew other people were critical”.
“I just heard like glass shatter, and everyone ran to the window because they thought it was a smash and grab, and there was just a gaping hole in the middle of the Apple Store,” Emily McKenna told the local station. I didn’t see the car drive by but someone said it was going pretty fast, so maybe he just lost control.”
