UPDATE 10/4: (More from Wellesley Police on this accident)
Wellesley Police were on the scene of a bad crash on Sunday night resulting from a car hitting a utility pole and downing wires that tangled up at least one other car (carrying kids, according to one source). Not surprisingly, the crash took place at Rte. 9 and Oak Street, an intersection notorious for accidents. The car that hit the pole swerved and hit a barrier and caught on fire; the driver was transported to the hospital in a ambulance, according to a source who shared the photo above.
The police live-streamed a bit of the activity, as you can see below.
