At least 20 people received minor injuries Tuesday afternoon after a tour bus rolled over on an Interstate 290 highway off-ramp, according to State Police.

The victims were taken to local hospitals with minor injuries, Trooper Scott Range said.

The bus rolled over about 2 p.m. on a curve on the off-ramp from Route 290 to Route 12 in Auburn. The bus can carry up to 60 people, but police were uncertain how many actually were on board, police said.

The investigation was continuing and authorities said they did not immediately have further details.
