The frozen lake where three boys died after falling in should have had more signs warning people of danger, a local councillor has said.
Marcus Brain, Councillor for Solihull Borough Council, said "there possibly should have been more signage" at the lake and "there should have been more buoys at the side".
His comments come after the first boy, 10, was named late last night as Jack Johnson.
He died alongside two other boys, aged eight and 11, after ice cracked at Babbs Mill nature reserve in Kingshurst, Solihull, on Sunday afternoon.
Hundreds of people attended a vigil for the boys last night as Jack's aunt revealed that her nephew had seen the other children fall through the ice and had tried to save them.
The fourth boy, six-years-old, remains in critical condition in hospital.
Cllr Brain told BBC Radio 4's Today programme: "In terms of reasonable foreseeability it would be very very difficult to predict something like this happening.
"My own observations are that there possibly should have been more signage, should have been more buoys at the side of the lake, but something like this is something that’s so unpredictable...so that probably wouldn’t have made an enormous difference."
He said that the local community "is in a state of utter and complete shock" following the deaths, suggesting that they happened because "they were playing near the ice".
"It looks like they were possibly playing football near the ice and that may have been what triggered them to go onto the ice."
Charlotte McIlmurray, Jack's aunt, wrote on Facebook late last night: "My nephew seen one go through the ice and he ran and tried to save them.
"We are just broken over it and to find out he died trying to save three lads he didn't even know, that just sums him up, he was amazing".
Another relative of Jack's told The Telegraph: "It has been the most devastating day in our family’s life."
