Police are looking for two 'people of interest' in the Tyson Bailey murder case.

They've released two videos of people seen walking into and back out of a building at 605 Whiteside Place.

Bailey was gunned down in the stairwell on the 13th floor of the building in Regent Park back on January 18th.

He was only 15 years old.

Toronto Police announced on Thursday they'd be going door-to-door inside the Toronto Community Housing building, to try and find leads in the case.

In the videos released, one shows Bailey walking into the building, followed by two others. The first person has been identified, and the second has not.

Both are considered of interest to police, and officers are now asking for help in id'ing the second person.
