LANHAM, Md. (CBSDC) — Police in the District say they have received reports of a mountain lion roaming freely in Southeast.

On two occasions 911 operators have received calls from concerned residents who claim to have seen the large animal.

The latest sighting came Wednesday night in the 3600 block of Highwood Drive Southeast, which prompted the city’s Office of Neighborhood Engagement to issue a public safety alert.

However, police say no officers are able to corroborate the reports and have not seen the lion firsthand.

Mountain Lion sightings in the District aren’t as uncommon as one may think. Two years ago authorities received a report of “large cat” prowling near Rock Creek Park.

National Park Service officials told The Washington Post they were highly skeptical of the claim at the time. Rangers and biologists say they found “absolutely no trace” of the animal.

In June, a black bear was spotted in Gaithersburg, Md. on three consecutive days before it was captured in neighboring D.C. a few days later.
