Andrew, what now after his arrest and release last week?

I don’t know enough about law to understand what will or may happen to AMW now. He was arrested and released. Does this mean anything? Will he be arrested again and charged in the future?
Or is there a chance that the hours he spent in the police station are the end of the matter?
Sorry to sound so naive but I really am.

Nobody knows what will happen next. It's with the police now. Probably best not to do too much guessing as we wouldn't want to prejudice any possible future trial

The police will compile evidence by sifting through his emails, his computer and any other material they may have recovered, and by talking to anyone mentioned in all that material. It might take months.
If there is enough evidence they compile a case and present it to the CPS. The CPS decide whether to prosecute on the basis of likelihood of getting a conviction, but also whether it is in the public interest, which will take into account any damage to national security and whether it is a worthwhile use of public funds.
Plenty of people spend months or years on police bail and under investigation. Nothing will happen quickly. If they have to read through 10 years of emails, that takes time.
I guess they will also consider what would happen if he were convicted. I really can't see them sending him to prison, he would be a walking target, but maybe I am wrong on that.

Thank you @Meadowfinch. That’s made me understand. Appreciate it.

What we know so far is that Andrew, like Mandelson, was arrested for misconduct in public office. There is also the possibility of him bring investigated for sex crimes, including sex trafficking.
