BOSTON (AP) — Massachusetts State Police say fire that destroyed a BoltBus approaching Boston on Monday likely began in the engine.
Spokesman David Procopio also said Tuesday an explosion that blew out the bus windows is believed to have been caused by a buildup of hot gases in the burning bus. He said investigators determined no passengers were carrying any hazardous material.
He said the bus made a maintenance stop in Connecticut during its trip from New York. It caught fire just before 5 p.m., eastbound on the Massachusetts Turnpike in suburban Newton. The driver and 47 passengers evacuated. No one was hurt.
The highway was briefly closed. The passengers were taken on two other buses to Boston.
Bolt’s parent company, Greyhound Lines Inc., says it is also investigating and cooperating with authorities.
Federal transportation authorities also will investigate.
