why was julie mugford detained by the police any ideas anybody.
Liz Rimington went to police indicating that Julie told her information that Julie did not provide to police when police had questioned her. The information at minimum showed Julie knew Jeremy killed his family. But it also coudl potentially have meant she was involved. She already didn't provide the information when they vountarily questioned her so why would they bother going to her house to voluntarily question her again?
They arrested her so she would have a motivation to talk.
They ended up letting her go not charging her which is what most people think of regarding an arrest. We usually think of an arrest meaning someone "booked" for a crime and tha tis largely thanks to TV and literature. But the law considers it an arrest when you are detained and the significance is that your right to a lawyer and right to remain silent are implicated by such and you have to be told of such rights.
The main significance of how it played out is that Jeremy defenders protrary this a s a case of Julie running to police after being jilted to harm Jeremy. In fact police went to her she didn't go to them and they went to her because a third party betrayed her confidence.
That sort of hurts the narrative Jeremy supporters would like to portray so it is not often admitted to or discussed.
