Stay off the ice!

That’s the message from local safety officials after five people reportedly filming a video fell through thin ice Monday afternoon.

Acton Fire and Police responded to Nara Park after receiving 911 calls that multiple people had fallen through the pond’s ice.

Upon arrival, the first responders saw that several people had emerged from the water. Those remaining in the pond walked out of the water under their own power.

The five people — three 23-year-old men, a 23-year-old woman, and a 30-year-old man — were taken to local hospitals for cold exposure and treatment. They were all expected to fully recover.

“Icy waterways in Acton are, at this time, absolutely not safe for any human activities including walking, skating, fishing, etc.,” the fire department said in a statement.

Fire Chief Anita Arnum issued safety tips to residents regarding ice and cold weather safety:
