Parents are demanding the detention of the owners of a Swiss bar that burst into flames at New Year, killing 40 people and injuring more than 100. 

Most victims of the blaze at Le Constellation were teens. 

Local authorities say the bar hadn’t had safety checks, investigations, or audits for five years. 

Europe Correspondent Jo McKenna told Andrew Dickens the French managers of the bar are being investigated for murder and arson.  

She says prosecutors and police say they’re not a flight risk, but there are demands for them to be detained.
