How long can police keep my iphone and tablet?

Got my iphone 5 and ipad taking of me for making a fake facebook account and started aguments, but it wasn't down on this it was done on my tablet but they still have got my iphone how long can they keep it for?

They're cops, doubt you'll get it back.

Contact them and ask… I didn't even know they could do that

As long as they wish unless you want to pay a solicitor to get it back!

They have the guns and the badges, I doubt you will ever see your possessions again.

@ Peace: It's in UK! Police have NO gun. But you've right as long as they want (need is the official term).
