Sands Bethlehem Casino Resort attracts 9 million visitors each year and is the only Pennsylvania casino to also have a 300-room hotel, an outlet mall and a concert venue.

The casino may be sold, employees were told Thursday, according to an email reviewed by The Morning Call. Sands Bethlehem employs about 2,500 people.

News of a possible sale comes four months after Sands Bethlehem President Mark Juliano told The Morning Call that the company planned a $90 million expansion that would add restaurants, slot machines and table games to the Bethlehem site.

Under the plan, Sands would create the largest gaming floor among the state's 12 casinos and expand its table games business.
