A dog has died after falling through the ice on a frozen lake in Middlesbrough, Cleveland Fire and Rescue have said.
Fire crews attended the scene and were shocked to see children playing on the same frozen ice the dog had just fallen through.
Cleveland Fire and Rescue posted on Facebook: "We have just attended an incident involving a dog that has fallen through the ice on Hemlington Lake, whilst in attendance children were seen trying to walk on the ice, please please pass on the dangers of this."
"Frozen ponds and lakes may be very tempting to walk or play on but please stay well away and do not put yourself or anybody else in danger."
In a later up date, fire services confirmed the dog had since died and they sent their sympathies to the owners.
They said: "This is another stark reminder to reiterate the message to stay well away from frozen ponds and lakes."
The incident comes days after four boys died after falling into a frozen lake in Solihull.
Siblings Samuel Butler, six, and eight-year-old Finlay Butler, eight, died along with their cousin Thomas Stewart, 11, and Jack Johnson, 10, West Midlands Police said.
They were rescued from Babbs Mill Lake, in Kingshurst, Solihull, near Birmingham, on Sunday and rushed to hospital.
The deaths of Finlay, Thomas and Jack were confirmed on Monday while Samuel died in hospital on Wednesday.
One West Midlands Police officer, a student response officer on one of his first operational rotations, suffered mild hypothermia trying to punch through the ice to reach the children.
West Midlands Fire Service area commander Richard Stanton said warned of the dangers of frozen lakes after the incident.
He said: "(Sunday’s) incident is a stark reminder to us all of the dangers of open water, especially during the winter months. Frozen lakes, ponds, canals and reservoirs can look picturesque but they can be lethal and there are no greater warnings of this than yesterday’s tragic events."
