A young mother crushed by a pallet of bricks that fell from 20m died in hospital two days later, it has been revealed.
Michaela Boor, 29, from east London, was left unconscious on the footpath in Mile End surrounded by piles of rubble on Tuesday morning.
She was understood to have dropped her son off at school across the road from the building site when bricks fell from scaffolding above.
A Scotland Yard spokesman said: "A 29-year-old woman who was critically injured after being struck by falling debris in Tower Hamlets has died.
"The woman died in hospital at 10.40am on Thursday. Her next of kin have been informed. Formal identification awaits. A post-mortem examination will take place."
Tragically, Boor is believed to have got engaged less than a fortnight ago to her partner of four years Andy Murgatroyd.
It has also emerged Boor's father Matthew Boor is a bricklayer who has been in the industry for 20 years. A fundraising page has been set up by his employers.
Building firm Maytrix Construction created a JustGiving page in a bid to raise £20,000 ($39,000) to help Matthew Boor and his family.
Before her death, a friend told the Evening Standard: "Her family are devastated, we all are. She has ended up fighting for life in hospital on her 29th birthday.
"We had seen pallets of bricks wobbling up there, it was just not safe. It could have been any of us. The family and all of us want answers."
A Health and Safety Executive spokesman said: "Inspectors have attended the site and are making ongoing enquiries in conjunction with the Metropolitan Police to investigate the circumstances of the incident.
"As the investigation is ongoing we are unable to comment further at this time."
