British police were searching for a "bomb factory" in Liverpool as they quizzed 11 Pakistani suspects arrested over a terrorist plot linked to Al-Qaeda.
The search for the terrorist bomb factory, which may have been used to store explosives, was being concentrated on a rundown block of flats east of Liverpool city centre, the media here reported.
Police stepped up its search operation following the arrest of a dozen al-Qaeda suspects, including 11 Pakistani who were in the UK on student visas, in raids in 14 properties across northwest England on Wednesday.
The terror suspects were questioned last night amid reports that they had planned a massive bomb attack within days, possibly as soon as Easter Monday.
Surveillance officers filming shopping centres in Manchester, which would be packed on a Bank Holiday, had seen some.
The 14 raids in Greater Manchester, Lancashire and Merseyside had to be advanced after anti-terror chief Bob Quick was photographed holding a secret document detailing the targets. Quick, 49, resigned on Thursday.
Far from studying, at least four of the suspects had been working as security guards, two at a large hardware store where the gang would have had access to potential bomb-making materials.
