BOSTON (AP) — State inspectors say they’ve found serious safety problems with buses used by a popular discount bus service operating between Boston and New York City and are asking federal transportation officials to declare Fung Wah Bus an “imminent hazard,” essentially shutting down the operation.

Department of Public Utilities Chairwoman Ann Berwick said that inspectors looked at nine buses used by Fung Wah Bus and found serious problems with eight, including cracks in their frames.
