B&Q is investigating claims a worker posted a sick tweet about the Solihull lake tragedy which left three boys dead and a fourth fighting for life.
The DIY giant was alerted to a tweet from an account which allegedly posted an offensive caption beneath a picture of the emergency operation at the scene.
The firm was sent a screenshot of what appeared to be the tweet alongside a picture of a man wearing a B&Q uniform.
It replied: "Thank you for bringing this to our attention. We are taking this very seriously and are investigating further.", reports Birmingham Live.
Three children - aged eight, ten and 11 - died despite hero rescuers smashing the ice at Babbs Mill Lake with their bare hands in a bid to save them on Sunday, December 11.
A fourth boy, just six, was fighting for his life in hospital.
One of them has been named as 10-year-old Jack Johnson. Another youngster was named locally in floral tributes as 11-year-old Thomas.
Following the Solihull incident, the emergency services urged people to stay away from potentially lethal water which had frozen over.
Yesterday, it was revealed a police officer waded into the frozen waters waist-deep and tried to punch through ice to save children.
Officers said they had received no reports of more missing children but would continue to search until they were certain no-one remained unaccounted for.
Supt Richard Harris, of West Midlands Police, said: “Police officers did go into the water. They were joined by other members of the other emergency services. Some of the officers went in waist-deep.
“One of my officers was trying to punch through the ice to rescue the children themselves. That officer, as a result of that, had some mild hypothermia yesterday. I’m pleased to say he’s now been released from hospital and he’s absolutely fine.”
