LONDON, Ont. - A lockdown implemented after a gun report has ended at a London, Ont., high school, and students have been dismissed from classes.

Police confirm no weapon was found inside Westminster Secondary School after witnesses in a passing vehicle reported seeing two men on the property with a handgun earlier today.

Emergency services were called to the school after several students went into “medical distress.”

Last Thursday, two students suffered serious injuries after being stabbed during a fight outside Sir George Ross Secondary in northeast London.

Another student was treated for minor injuries after being struck in the head with a metal pipe.

Three teens are facing charges in that incident.
