Fort Collins residents near Mason Street and Mulberry Street were told to hunker down Friday evening after police issued a shelter-in-place order for the neighborhood and shut down part of a key downtown corridor. A heavy police presence moved into the area and closed Mason Street between Mulberry and Myrtle, snarling traffic around the edge of downtown. Officials have not said what triggered the response, only that officers were dealing with an active situation.
In a 7:40 p.m. post on X, Fort Collins Police told anyone already in the Mason-and-Mulberry area to shelter in place unless directed otherwise and urged everyone else to steer clear. The same update confirmed that Mason Street was closed between Mulberry and Myrtle while officers worked the scene.
Police Alert And What We Know
Local outlet Denver7 reported on the department’s post and confirmed the Mason Street closure, noting that officials had not released any additional details about the situation. Denver7 described the incident as developing and said its newsroom was continuing to monitor police updates.
Where This Is And Who It Affects
The intersection of Mason and Mulberry sits on the east side of downtown, close to Colorado State University and several major transit routes. That means the closure is likely complicating access to campus and slowing bus service while the response is underway. Route information from Transfort shows local lines and the MAX corridor running through the Mulberry and Mason corridors, which could mean detours or delays until officers clear the area.
If You Are In The Area
Police have asked people nearby to stay indoors unless they are specifically told otherwise and to follow instructions from officers on scene. Anyone in immediate danger should call 911. For non-emergency questions, the city lists a police non-emergency line and media contact on the Fort Collins Police news page. Officials are also urging the public to avoid the area until the shelter-in-place order is lifted.
Developing Coverage
This is a developing story and details are still limited. Updates are expected as Fort Collins Police release more information and local outlets verify what is happening at the scene. For the latest, residents can follow the department’s feed on X and check ongoing coverage from area newsrooms tracking the situation.
