The arrest may be made with or without a warrant, depending on the circumstances. The plaintiff's claim in a warrantless false arrest lawsuit arose from a sheriff s deputy s visit to her house to check on the welfare of her daughter.If you are arrested without probable cause and falsely charged, can you sue the arresting officer? How would you go about doing this? A peace officer may make a valid arrest without a warrant in certain circumstances other than those set out in this instruction. Sometimes the police need a warrant to conduct a search or make an arrest. False arrest is one of the most common types of false imprisonment. An officer must either have a warrant or reasonable suspicion that a person has committed or is about to commit a crime (probable cause). You have the right to not be arrested or handcuffed without "probable cause" to believe that you have committed a crime. It is well-settled that the fourth amendment allows for warrantless arrests outside the home as long as the police have probable cause to arrest the suspect.
