A tip line helped police solve 10 Fairfax County bank robberies in a year’s time, according to the department.

Most recently, the Crime Solvers line led authorities to a man suspected in three recent robberies. Woodbridge resident Marcos Francisco Pacheco, 46, was arrested Wednesday for allegedly holding up a Wachovia Bank on Richmond Highway twice within a week’s time in late October, as well as a BB&T branch earlier this month.
