can i sue over a year later after being arrested for askinf to have an appointment to speek with chief of police?

The statute of limitations for this type of claim (false arrest) is two years from the date of occurrence (Oregon Revised Statutes 12.110(1). The Oregon Supreme Court recognizes "false arrest" as a synonym for "false imprisonment." (Hylton v. Phillips, 270 Or 766 1974). If addressing this in state court, a tort claim notice was required to be filed within 180 days of occurrence (ORS 30.275(1)(2)(b). It appears you would be past that date. However, a civil rights claim (42 USC section 1983) filed in federal court still has the two year statute of limitations but the tort claim notice requirement does not apply (Felder v. Casey, 487 US 131, 1988)..
