A quick chat with the police – or an interview? You need a lawyer – Legal Voice
‘When the police investigate a criminal offence, it may not be necessary to formally arrest a suspect. In the past, it would be common practice that those being questioned by the police were arrested. Now, with the introduction of the 28-day bail limit, it is becoming a more accepted method for the police to question suspects by way of a ‘voluntary interview’.’
