A prosecutor’s office in Peru said it was investigating the death of two employees in a McDonald’s restaurant in the capital Lima following protests against hazardous work conditions at the U.S.-based fast-food giant.

Police said employees, Alexandra Porras, 18, and Carlos Gabriel Campo, 19, were electrocuted on Sunday while cleaning the kitchen.

Lawyers for the Campo family told BBC Mundo that the floor was wet when the bodies were found.

The family also complained about 12-hour shifts exceeding the legal cap in the country of 8 hours.

Another investigation is set to be launched by the Labor Ministry.
