A mountain lion lounging in a tree prompted Westminster police to shut down a stretch of Eaton Street between 112th and 113th avenues Tuesday morning, sending officers to the residential block and asking neighbors to steer clear of the animal.

The Westminster Police Department announced the closure shortly before 10:30 a.m., according to The Denver Post, which reported that the mountain lion was spotted lounging in a tree in the area. The closure sits in a residential area west of Sheridan Boulevard, and police said they notified neighbors and posted officers on scene while the situation played out.

Police asked residents to avoid both the closed block and the animal itself, according to the same report, as the incident unfolded Tuesday.

The Eaton Street closure is in a residential area of Westminster, where a mountain lion was seen in a tree above a neighborhood street.

The article also describes two individual encounters this year. In May, Colorado Parks and Wildlife officers tranquilized and relocated a young male mountain lion after a homeowner's security camera captured it wandering across a backyard deck in Centennial, as Hoodline previously reported. In April, wildlife officers in Salida tranquilized and relocated a young lion after it slipped past an elementary school into a nearby neighborhood, according to the Denver Gazette.
