Lockdowns have been lifted at three local schools.

Waterloo Regional Police said hold and secures were put in place Tuesday morning after someone called Alpine Public School in Kitchener, Ayr Public School in North Dumfries and Baden Public School in Wilmot Township and threatened violence.

“They are similar in nature, came in around the same time and detectives are currently investigating,” police explained in an email to CTV News.

All three schools were locked down as a precautionary measure, then called off just before 11 a.m.

“The investigation remains ongoing and more information will be released when available,” police said in an updated post.
