SIDNEY - The Sidney Police Department confirmed a mountain lion sighting one block east of the North Elementary school early Monday morning. 

Police Chief Joe Aikens said the cougar was spotted on a resident's security camera at approximately 1 a.m. on the 1400 block of Elm Street.

The resident who captured the video of the big cat told police they looked out the window and saw the mountain lion take off to the north before disappearing out of sight. The video footage was turned over to authorities. 

Sidney Public Schools sent a digital alert to parents Monday morning about the mountain lion sighting. They announced North Elementary students would stay inside until they had the "all clear" from authorities to resume outdoor activities. 

Sidney Police are working with the Cheyenne County Sheriff's Department and the Nebraska Game and Parks to take proper measures in preventing the mountain lion's advancement further into the community. It has not been captured. 

Aikens says residents should be vigilant and keep an eye on children and pets. He advised not to leave food and water outside. With how dry it has been in the Sidney area, animals outside of town are seeking food and water resources within city limits. 

If you spot the mountain lion, you're asked to immediately call 911 or (308) 254-5515.
