One of the ongoing anomalies of the law enforcement system is that it's perfectly lawful for the police to carry on any investigation they see fit, for as long as they like, provided they do not employ tactics such as surveillance, wiretapping, postal/internet interception etc, which require justification and senior-level authorisation or court orders. Technically, there's nothing whatsoever - outside of budgetary or political considerations - to prevent the police from carrying on an ongoing investigation into the Acourt brothers, Sion Jenkins, Fhimah, the Guildford Four, or anyone whatsoever for that matter. This could involve questioning of the individuals (although not under compulsion), questioning of friends/colleagues/family (likewise, not compulsory), monitoring of addresses, known associates, affiliations etc.
It doesn't even need to get to the point of charging someone. Look at what's being done to Lamin Fhimah at the moment. The poor guy is reportedly terrified, and that just on some press reports of what Mulholland has been saying.
