Several people are in critical condition after being rescued from a frozen lake in Solihull according to police.
A serious incident has been reported in Babbs Mill Park, Fordbridge Road, in the Kingshurst area.
According to West Midlands Police, several people were taken to the hospital.
Emergency services from the West Midlands Fire Service and the West Midlands Ambulance Service are also present.
The nature of the incident had not yet been confirmed, according to police.
Concerned members of the community gathered near the scene in what is a residential area, as emergency services carried out work at the lake.
It was likely that the emergency service presence would remain there for a number of hours, they added.
Babbs Mill Park is a local nature reserve with a lake, river, wildflower grasslands, and woodlands.
Temperatures of 0C (32F) are currently being reported in the area and are expected to plummet to -3C (26.6F) during the night.
The incident came as police in Cumbria said they were dealing with an “incident” at Siddick Pond in Workington.
