Concerns have been raised by parents, fans and teachers on what happened at Prince Charles Park on Saturday.

The lights went out during the Coke Zero Deans under 18 semifinal between Assemblies of God High and Queen Victoria School with five minutes from full time and QVS was leading 10-5.

Fiji Secondary Schools Rugby Union President Paula Motu said they understand the concerns and they are still awaiting a written explanation from the Nadi Town Council.

Motu said they didn't expect that to happen and they were not ready for it.
