A Greyhound bus driver charged with bank robberies in Maine and Rhode Island was in a Bangor courtroom today, where he waived his detention hearing.Meanwhile, the FBI continues to investigate to see if Robert Ferguson is the so-called “burly bandit” wanted in nearly a dozen bank robberies throughout new england.The 47-year-old Lowell, Massachusetts man had a detention hearing this afternoon in federal court in Bangor. He was arrested Wednesday and is accused of holding up a Bangor Savings bank in Orono the day before.He was later charged by police in Warwick, Rhode Island, for a bank heist in that city in late May. The FBI is probing to see if he’s the same person suspected in at least ten bank robberies in Massachusetts, Rhode Island, Connecticut and New Hampshire since April.Ferguson will remain at the Piscataquis County Jail until his arraignment in August. His defense attorney says his client would not have been able to afford bail which is why he waived today’s hearing. “I think they would have considered him a flight risk, although I don’t think he really is,” says attorney Jon Haddow, “and so I think they would have set bail pretty high anyway, if she even granted one at all and given the warrant in Rhode Island it simply doesn’t make sense to have a hearing.”He’s being held without bail at the Piscataquis County Jail until his arraignment in August.
