A Connecticut family made up claims that it rescued three immigrant relatives from a kidnapper by showing up with baseball bats at a ransom-exchange meeting, according to police reports.

Instead, the reports say, the family had arranged transportation to Connecticut for their relatives after they entered the country illegally and a melee broke out when a driver asked for an additional fee of $60 per person to take them to the family’s home.

Police say they detained nearly 20 people after the Aug. 2 fight in a Greenwich shopping-center parking lot.
