A few weeks police in Birmingham arrested eight people, who were later charged with terrorism offences and seven men kept in custody:
Four of the men were charged with preparing for an act of terrorism in the UK, and two with failing to disclose information.

This week four young men were arrested, in part two of the investigation, now known as Operation Pitsford and they too have been charged:
They are accused of collecting money for terrorism, travelling to Pakistan for terrorism training and travelling abroad to commit acts of terrorism. They have been charged with engaging in conduct in preparation of terrorist acts contrary to section 5(1) of the Terrorism Act 2006, a force spokesman said.
