Guests at the Ramada Inn in Windsor Locks were evacuated for about 45 minutes on Thursday morning because of a strong smell of gas.
The incident was reported around 5:30 a.m. at the hotel, which is located near Bradley Airport. Gas was found to be leaking from a kitchen appliance in the back of the building, according to officials.
After the leak was contained, fans aired out the area.
Yankee Gas metered the hallways and hotel rooms, determined that the levels were normal and the guests were allowed back inside.
What caused the leak is not known.
