1224pm EST. University College Hospital in London is now on “high alert” as London police search for today’s terror bombing suspects. All four bombing locations have been cordoned off. Intelligence sources telling Fox News’ Simon Marks that the mastermind of the 7/7 bombings is not in custody and still at large.
The latest from the Guardian on the hospital search:
Armed police have resumed searching a hospital in central London amid reports that a suspected would-be suicide bomber was on the run inside after explosions on tube trains and a bus today.
Officers went back into University College Hospital (UCH) an hour after calling off their original search, which came after an incident involving explosives at the nearby Warren Street tube station.
Speaking at 4.50pm, a Metropolitan police spokesman said: “We have armed deployment at UCH, but we are not prepared to discuss this further at this stage.”
At 4.30, the Sky News television channel reported that a convoy of police vans and two armed response units had arrived at the hospital, including officers from the anti-terrorist branch.
The report said a patient had seen around 30 armed police inside the building.
Sky News earlier reported that a memo had been sent to hospital staff, at the request of the Metropolitan police, asking them to be on the lookout for a black or possibly Asian man, 6ft 2in tall, wearing a blue top with wires protruding from a hole in the rear.
Staff had been told to call 999 if they saw the suspected bomber, but not to approach him.
