FITCHBURG, Mass. (AP) — A grand jury has indicted a Fitchburg man accused of punching a pedestrian who had yelled at him for driving too fast, a blow that led to the man’s death.

Prosecutors tell The Sentinel & Enterprise (http://bit.ly/U9xaZC ) that 51-year-old Glenn Lowell was indicted on charges of manslaughter and assault and battery causing serious bodily injury.

An arraignment date has not been scheduled.

Authorities say 50-year-old Gregory Spyropoulos (spuh-ROPP'-uh-liss) was crossing a street in June when he yelled at Lowell for driving too fast.

Police say Lowell stopped, got out and punched Spyropoulos, who fell to the ground and suffered a head injury. He died at a hospital three days later.

Lowell surrendered to police after reading about Spyropoulos’ death and has expressed remorse, saying Spyropoulos threw the first punch.
