As per a report published in the guardian, the British Security official could figure out the connection between the al-Qaeda commanders in Pakistan and people in Britain. They could achieve this after monitoring calls and emails based on the inputs provided by MI6.
"There was concern al-Qaeda was directing operations, recruiting people to travel to this country, direct their operations and tell them what to do," sources said.
Investigations pointed to an imminent attack being planned on British soil, this lead to the subsequent arrest of the people under the scanner. Two of the men arrested were seen taking photographs of crowded places in Manchester, a necessary step terrorists take before planning an attack.
However, the security agency has failed to come out with something substantial regarding the arrests of 11 Pakistani nationals even after more than forty-eight hours.
Sources said the officials had failed to find any bombs, bomb-making parts, precursor chemicals to make explosives, weapons or ammunition till now. The investigative process has started and involves scanning the computer hard disks recovered from Manchester, Liverpool and Clitheroe.
The operations are at a early stage, after the officials have put together all the evidence then the whole plot can be revealed said the investigators.
