Authorities now say two people were involved in an incident at the AbitibiBowater mill in Fort Frances Sunday that left a 15-year-old girl with serious injuries, including burns to her body.
Ministry of Labour says the two scaled a fence late Sunday evening and one made contact with a source of electricity.
When emergency personnel arrived on scene, the 15-year-old was found in a fenced off area near a power transformer.
The Electrical Safety Authority is also assisting O-P-P in the investigation.
