A 58-year-old man who just happened to be bicycling past saved the life of a teenage girl who had fallen through the ice of a pond in Hanover Thursday afternoon, said Hanover Fire Chief Jeff Blanchard.

Richard Cullen of Scituate was biking by Forge Pond when he heard a girl’s screams. Initially disregarding them, Cullen thought about it and turned back to see a break in the ice and the 14-year-old Hanover girl’s head poking out, Blanchard said.
