The reality TV personality was apprehended by authorities at the Club Habanos nightclub in Fresno, California in the early hours of Sunday (January 15).
Kahl - who appeared on Ali Fedotowsky's season of the dating contest - was released from a local police station after a few hours, according to TMZ.
The website reports that he had been involved in "an incident" at the venue, but further details have yet to emerge.
Kahl is known to have split with Bachelor star Vienna Girardi in November. The couple met while competing on the second season of ABC's Bachelor Pad last summer.
The couple attempted to salvage their romance on Style network show Relationship Rehab in December, but Girardi stormed off during filming when confronted by another ex-boyfriend.
