Officials who managed Khan after he was freed and participated in public protection meetings have said they did not know about the attack-planning intelligence.
Kenneth Skelton, Khan’s probation officer, previously told the inquests that if he had been told, “the whole management process would have been altered”, potentially including the decision to let Khan attend the event where he launched the attack.
Detective Chief Inspector Ryan Chambers, of the West Midlands Police Counter-Terrorism Unit, said he had “no reason to think” that probation and other agencies did not know of Khan’s feared intentions.
DCI Chambers was the senior investigating officer for the covert investigation into Khan, which was conducted alongside MI5.
