Four boys drowned after falling through a frozen lake and spending 20 minutes under the ice while "playing", an inquest has heard.
Siblings Samuel Butler, six, and eight-year-old Finlay Butler, eight, died along with their cousin Thomas Stewart, 11, and Jack Johnson, 10, on December 11.
They were rescued from Babbs Mill Lake, in Kingshurst, Solihull, near Birmingham, and rushed to hospital.
