A police officer who monitored Fishmongers’ Hall attacker Usman Khan after he was released from prison has told a jury she was “shocked” by how friendly he was. Constable Victoria Barker, from the counter-terrorism Prevent team with Staffordshire Police, said she had expected Khan to be aggressive and anti-authority but he was “the complete opposite”. She met Khan three days after his release from prison in 2018, after he served eight years for his part in a plot to set up a terrorist training camp in Pakistan. Khan murdered Cambridge graduates Jack Merritt and Saskia Jones at a prisoner education event at Fishmongers’ Hall in the City of London in November 2019.
