A Fall River man was arrested in connection with an indecent assault of a woman in the North End early Saturday morning, police said. Nieto Wagner, 36, was arrested Saturday night in Fall River by the Boston police fugitive unit, said police spokeswoman Neva Coakley. Around 2:35 a.m. on Saturday, a woman was walking near Tileston and Wiggin streets and noticed a man following her, police said. The two spoke briefly and the man grabbed the victim in an indecent manner before running off. Wagner is expected to be arraigned on charges of indecent assault Monday in Boston Municipal Court, Coakley said.
