The RCMP in Pictou County is asking for the public’s help in locating two missing children who went missing Friday morning.

The RCMP says six-year-old Lily Sullivan and four-year-old Jack Sullivan were last seen on Gairloch Road in Lansdowne Station in Nova Scotia’s Pictou County around 10 a.m.

The force confirmed with CTV News the children are very well known to each other and were last seen at the same home “before they wandered.” However, police would not confirm their exact relationship.

Multiple agencies are taking part in the search, including ground search and rescue teams, the Civil Air Search and Rescue Association, the Department of Natural Resources Air Services, and several RCMP units.

“A vulnerable missing person alert was issued for Pictou County this morning to help find the two,” reads a Facebook post by Nova Scotia RCMP.

Police describe Lily Sullivan as having shoulder-length light brown hair with bangs. The force says she might be wearing a pink sweater, pink pants, and pink boots.

Jack Sullivan has short blondish hair and was wearing blue dinosaur boots. Police say no other clothing description is available at this time.

The RCMP is asking the public to spread the word on social media and to avoid the search area to allow trained searchers to do their work.
