Part of a wider conspiracy, security officials believe
The disclosure that the British-born Muslim convert was likely to have been part of a wider conspiracy came as armed police detained 11 people in raids across the country with two of the arrests, including that of a woman, described as “significant” in the investigation.
Three cars were also taken away for forensic examination. Police are still hunting associates of Masood who are believed to be linked to the Westminster attack.
It has also emerged that 52-year-old Masood used the Whatsapp messaging service just minutes before he smashed his hired Hyundai car into the railings at the Houses of Parliament.
