A woman who spoke to CTVNewsNorthernOntario.ca and asked to remain anonymous said she was at the Marcel and Jane Labbé Arena in Sturgeon Falls with her kids on Saturday when the altercation happened.
During the U18 game between the Markstay-Warren Wolves and Don's Butcher Shop West Nipissing Stings, one of the moms from the Stings team allegedly started 'chirping' the other team, making comments about how it took them four years to finally beat them.
"The victim is known to cause verbal altercations during her children's hockey games," the witness said.
"The 'victim' harassed the opposing team the whole last period and was told repeatedly to quiet down and leave them alone."
Fans from Markstay-Warren asked her to stop and leave them alone, she said.
Things became physical when one of the Wolves' moms hit the woman with a cowbell.
As a result, a 40-year-old Markstay-Warren woman has been charged with assault with a weapon, assault causing bodily harm and mischief by destroying or damaging property.
She is scheduled to appear in court April 4 in North Bay.
