The Bikini Bottom Police Department (BBPD) is the main law enforcement entity in Bikini Bottom. This includes officers, wardens, prison guards, SWAT Team, and riot guards. Their headquarters is the Police Station.
The Bikini Bottom Police Department has established multiple locations to base their operations, as well as places to contain offenders of the law. However, in many cases, it is unreasonably stricter than in real life.
The station is where the cops stay and receive calls for crimes, which is seen in "Life of Crime." They have a dispatcher unit somewhere in a different building of Bikini Bottom as well.
The jail holds the regular criminals, for simple crimes such as littering, as the The Tattle-Tale Strangler had to stay for littering outside of the Krusty Krab. It holds major criminals as well, such as Plankton for trying to steal the Krabby Patty Formula, in which he has a pad-locked cell, which he easily breaks out of (as seen in "Krabby Road").
Inferno Island is a high security prison, located in the middle of a body of water. The only way to get to it is to go there from the dock-yard, on a metal boat, to make sure there are no possible ways for prisoners to escape and swim to shore. The island is very harsh and the prisoners must sleep on hard beds with flat pillows. Inferno Island is much like Alcatraz Island, a prison island from the early to mid 1900's that was strangely abandoned. Alcatraz was near land, had jagged rocks around it, and prisoners were transported to it by boat, the beds were hard, there were watch towers, much like Inferno Island.

"Doing Time" - Arrested in one of Mrs. Puff's dream sequences.
"Party Pooper Pants" - Arrested apparently because he didn't invite the police to his party (possibly making them believe his party was illegal), and spent a night in a police office. The initial reason was for attempting to break into his own house.
