A police officer tried to punch through ice on a frozen lake to try and save children stuck below.
Three boys aged 11, 10 and eight years old died after falling into icy water on Babbs Mill Lake in Solihull on Sunday afternoon.
A six-year-old boy also remains in critical condition, while officers have played down fears that others were trapped in the lake after nearly 24 hours went by without anyone else being reported missing.
Members of the public and police officers initially went into the chilly waters to save the boys. The officer who punched the ice had mild hypothermia after the rescue attempt, West Midlands Police saidWhen they were eventually helped out of the lake by specialist water-rescue trained fire crews, the children were found to be in cardiac arrest and were sent to Birmingham hospitals, where they all arrived in critical condition.
West Midlands Fire Service area commander Richard Stanton said the deaths of the three boys were a tragic reminder of the dangers of open water.
