Authorities in Maine have warned the public about snakes after a large snake skin was found near the Presumpscot River on Saturday.

Westbrook police said they have been searching for a 10-foot snake since June after a woman reported seeing it near a playground. There have been several other sightings of the reptile, dubbed “Wessie,” since, according to WMTW-TV.

The snake skin was found near Riverbank Park at around 3 p.m., Police Chief Janine Roberts said.

Police are trying to determine the type of snake.

“Until the type of snake is determined and we can assess the safety risk, we caution people who recreate along the Presumpscot River to remain alert, maintain a safe distance from any wildlife, and report any sightings of the snake to the Westbrook Police Department,” authorities said in a statement.
