If they're bailed then they must have been charged with something (i think) otherwise they will have been released without charge. They must be a suspect in whatever they've done.
You have to pay some money to be allowed to be free until the date of your trial (so people who are bailed will go to court/have been charged). If you're a dangerous criminal or the judge or whoever thinks its likely you'll run rather than go to court you're denied bail, you have to remain in prison till your trial but the time you serve then is knocked off your sentence (I think).

Requiring surety is by no means a certainty, in fact if I'm remembering correctly it's not even all that common. Besides, police bail doesn't involve it, only a Magistrate can impose it.
