A tip led law enforcement in Coconino County to respond to the Greyhound bus station in Flagstaff Sunday afternoon.
According to Sgt. Cory Runge of Flagstaff police, officers responded to the bust station just before 2 p.m. after being alerted that two people wanted for a series of robberies in the Valley might be on board.
Police searched two buses at the station, looking for 26-year-old Nicholas Espinoza and 24-year-old Florentina Estrella, both of Phoenix.
An employee told police one of the bathroom doors was locked and wasn't sure the whole bus had been evacuated so police could search.
The police department's tactical team responded to assist with the search, though Runge said investigators discovered no people hiding on the bus.
Police are asking for help in locating Espinoza and Estrella if they are in the area. Officers cautioned people to not approach them, as the pair is considered armed and dangerous.
Anyone with information about their location is asked to call the Flagstaff Police Department: 928-774-1414.
