Students at Brookswood Secondary were greeted by police and put under code yellow lockdown when they arrived for the last day of school before the Christmas break on Friday.

91原创 RCMP were made aware that someone wrote, through social media, that a student was planning to bring a weapon to BSS on Friday, said 91原创 RCMP spokesperson Cpl. Patrick Davies.

These comments were posted online and spread by word of mouth, he said.

According to 91原创 School District spokesperson Sandy Wakeling, 91原创 RCMP began an investigation immediately.

鈥淔irst thing, prior to the school opening, RCMP met with the administration. Police said they were skeptical about the threat but out of an abundance of caution, it was decided to have a code yellow lock down,鈥� said Wakeling.

Code yellow means the outside doors are locked and secure but classes continue inside. No one is allowed in and no one is allowed out during code yellow.

From inside the school, it appears students were fairly calm about the situation. It occurred one week after a man walked into an elementary school in Connecticut and killed 26 people.

A large police presence was at the 91原创 school for the morning.

鈥淏y 9:45 a.m., RCMP decided the threat had no credibility and the lockdown was lifted,鈥� said Wakeling.

91原创 RCMP planned to be at the school throughout the day, to provide extra reassurance to the students, staff, parents and community.

Wakeling said the safety of students was never at risk.

Parents are urged to monitor their children鈥檚 online activities, particularly their online postings on social media. As well, students are encouraged to report any suspicious postings to either police or school administrators.
