NORWALK, Conn. (AP) Authorities say a man who was stabbing passengers on a casino-bound tour bus on Interstate 95 in Connecticut has been fatally shot by state police.

State Police Lt. Paul Vance says the unidentified man began attacking passengers late last night. The bus driver flagged down a trooper at a construction site.

Vance says the suspect was acting aggressively toward the trooper and was shot when he refused to drop his weapon, a ``cutting instrument.''

He died at a hospital. Two people were stabbed and another person suffered non-life threatening injuries after being accidentally shot by the trooper. The trooper wasn't injured.

The bus, carrying about 24 passengers, was headed from Chinatown in New York City to a Connecticut casino.

The northbound lanes of the interstate were closed late Tuesday night, and were reopened early this morning.
