Hold-and-secure at Ancaster high school lifted after report of armed person

A brief hold-and-secure at Bishop Tonnos Secondary School has been lifted Friday afternoon following a report of a person with a weapon.

The Hamilton-Wentworth Catholic District School Board says the high school in Ancaster was placed into a hold-and-secure around 1 p.m. as a result of an incident outside.

The hold-and-secure was lifted nearly an hour later, and officers say the person did not enter the school with the weapon.

Officers say it was only reported that the person was seen with a weapon outside of the school.

UPDATE: The hold and secure at Bishop Tonnes Catholic Secondary School has been lifted.
Hamilton Police remain on scene as we continue to investigate this incident. Thank you Hamilton.
