CCTV from outside a Liverpool hospital shows the moment an explosion ripped through a taxi
CCTV footage appears to show the moment a deadly explosion went off inside a taxi arriving at Liverpool Women's Hospital.
Four men have been arrested under the Terrorism Act after the deadly blast at 10.59am on Remembrance Sunday.
The male passenger, yet to be formally identified, was declared dead at the scene.
The taxi driver, named locally as David Perry who works for Delta taxis, one of the city's largest cab firms, is now recovering at home with his wife after being treated at hospital, ITV News understands.
His actions have been hailed as heroic for helping to avoid further casualties. A friend claimed Mr Perry got out of his cab and locked the man in the vehicle after apparently noticing an explosive device.
What does the CCTV footage show?
In the footage, a black taxi is seen approaching the hospital building before a blast rocks the car - sending debris flying towards the reception area and thick smoke billowing.
Mr Perry can be seen escaping out of the driver car door while onlookers nearby and from within the hospital rush to the scene.
What do we know so far?
Police on Monday said the taxi passenger appears to have made an improvised explosive device, which caused the blast.
Three men have been arrested under the Terrorism Act. Counter Terrorism Police North West said the men – aged 29, 26, and 21 – were detained in the Kensington area of the city.
The three arrests took place in Sutcliffe Street in the Kensington area of the city, where witnesses reported seeing armed officers swoop on a terraced house.
Armed police evacuated homes on Rutland Avenue in Sefton Park overnight on Sunday, with counter-terror officers sighted in the neighbourhood.
Police arrested a fourth man, aged 20, on Monday - again in the Kensington area of the city.
The taxi explosion “has been declared a terrorist incident” but the motivation is “yet to be understood”, police said in a press briefing on Monday.
