Friedrichshafen (dpa / lsw) - At the Seehasenfest in Friedrichshafen, a grill caught fire in a sausage stand on Monday. Four people were slightly injured by smoke gases, the police said. They were treated on an outpatient basis. The investigators assume the cause of a technical defect in the gas supply. The sausage stand made of wood burned down. The amount of damage has not yet been determined. A tree was also affected. An adjoining marquee and the access roads for the fire engines were cleared. As the city announced on Facebook, the festival will continue as planned.
