After becoming free, Crean said he managed to lock himself in a toilet, adding: “I smiled, then middle-fingered him, then closed the door.”
He then called 999 “probably for the first time in my life”, and only came out when he heard the police walkie-talkies.
Asked about how Williams appeared, Crean said: “100% he was fine, he looked normal, he was just on a mission, he didn’t seem angry.”
Williams is also accused of attempting to murder Raza Aslam, Sachin Balakrishnan, Scott Bletcher, Kevin Deely, Scott Green, Jonathan Gjoshe, Michael Paffett, David Presland and Samir Zitouni on the London-bound train between Peterborough and Huntingdon on 1 November.
Prosecutors further allege that on 31 October, Williams tried to kill three people in Peterborough, before attempting to murder a teenager in the early hours of 1 November on a DLR train in east London.
Whether Williams carried out the attacks is not in question – the court has been told – but jurors must consider whether he intended to kill.
The trial continues.
