One often comes across, in fact and fiction [eg in tv cop shows] people being 'taken in for questioning'.

I have often wondered whether the police can compel anyone who is not under arrest to attend a police station. The following solicitor's online advice

"If the police suspect you of having been involved in a criminal offence they can arrest you or request you voluntarily attend a police station in order to be formally interviewed on tape and under caution"

suggests that attendance is voluntary, as is the answering of any question.

But what would happen if one refused to attend? ~ esp if the police did not think they had sufficient grounds to arrest?
