North Bay police have arrested one of two men in connection with a robbery earlier this month. But they are still looking for 18-year-old Isaac Ashfield. An arrest warrant is out on Ashfield for extortion and two counts each of robbery with violence and forcible confinement. An 18-year-old North Bay man was arrested Monday morning on the same charges. The robbery took place in early December and police say both of the accused know the victims.
