They already know. The same thing happened to someone I know in the UK, a few years back. He was arrested at dawn and put in a cell for a whole day after an offence was committed from the IP address under his control. He said the officer interviewing him admitted he understood that the offender and node owner were probably different people, but it was close enough to justify an arrest. This was a high-profile case where they did actually find and arrest the actual offender, so they had real leads - could only conclude this was intimidation.
