Update 6am Monday:

We are expecting an update from Thunder Bay police Monday about what may have been happening at the Marina.

A number of police cars were seen Sunday afternoon and that included a police dog and an OPP van.

Officers were on the side of where the Spirit Garden is located. The path to the garden was closed for a time but is now open.

Police have left the scene. There is no indication why they were at that location in the first place.
