A school in Saskatoon's Stonebridge neighbourhood is advising parents to speak to their children about strangers after a man approached kids on several occasions.
In a letter sent to parents on Friday and obtained by CBC, Chief Whitecap School officials warned parents of a man who had talked with students in four separate incidents, asking them about their vaccine status and urging them not to get immunized.
The letter said he has approached students during school hours and after school.
"On Thursday, a few senior students reported to a staff member that a man had approached them during recess while they were playing in the park behind the school," the letter said.
He was also seen on school property again Friday morning, according to the letter. Chief Whitecap staff said that they had contacted the police — as well as the nearby St. Kateri Tekakwitha Catholic School — about the incidents.
"We are proud of our students for reporting this situation to staff members. In light of this incident, I ask you to remind your children to stay alert and safe," the letter said.
The Saskatoon Police Service said via email that it received a call about the suspicious man at about 10:15 a.m. CST Friday morning and is investigating.
Police say the man was also advising children to remove their masks.
Police are asking anyone who has experienced a similar incident to contact them.
School staff told parents to remind their students never to talk with strangers, inform a trusted adult if they see something concerning, never to get into a vehicle without parental permission and to walk in a group.
CBC News has contacted school administrators to learn more information.
