A mysterious release of pepper spray at a Wendy's restaurant in Northeast Philadelphia sent 41 people to hospitals yesterday.
City police and the Fire Marshal's Office were trying to determine whether the incident was accidental or intentional, Capt. Mike Carroll, a fire department spokesman, said last night.
No one was seriously injured, Police Lt. Mark Bugieda said.
Carroll said emergency medical technicians responded to a report of fumes at Wendy's at 2:18 p.m., and a woman at the restaurant complained of nausea.
