It was like a lower budget version of Sam Jackson's cult favorite movie 'Snakes On A Plane', except is was a bus from Atlantic City to New York and it was cockroaches. One of the passengers, Dawn Alexander, told a Jersey TV station it was like a scene from a horror movie -- "There's like a thousand roaches. And when I say infested, I mean infested. People were in the aisles literally brushing roaches off of them."

"I sat down... roaches started crawling up on our clothes, falling down from the ceiling. Everything," said another.

Greyhound's Media Relations Director Maureen Richmond said the bus driver acted with urgency when the passengers alerted him to "bugs on the bus."

"He immediately pulled the bus over and radioed our dispatch office for assistance”

Greyhound sent another bus immediately and provided full refunds.

The insects poured from vents and the ceiling spreading from back to front. What caused the 'attack' is not yet clear and Greyhound's plans to get rid of them have not been revealed.

"We are investigating how they got there -- in bags or from the bus," said Richmond.
