Experts from the 9/11 terror attack have been brought in to give specialist knowledge to the police investigation into the Grenfell Tower fire.
Experts from 9/11 attack helping Grenfell investigation
Metropolitan Police Deputy Commissioner Craig Mackey said the extraordinary size of the potential crime scene meant those who worked in the aftermath of the Twin Towers disaster in 2001 were being called upon.
Mr Mackey said the 200 UK officers already working on the case were faced with sifting through 15 tonnes of debris on each of the building's 24 floors.
Giving an update at the London Assembly Police and Crime Committee, Mr Mackey said:
This is one of the most complex recovery operations we've seen.
The people we're taking advice from - which gives you an idea of the complexity - are some of the people who worked on 9/11 and the fall of the Towers.
It is an extraordinary size of crime scene.
