We're police. You're free."Police said they had arrested four people in the town of Casarrubios del Monte in the central province of Toledo and another in Madrid in connection with the incident.The victim, who has not been named, was kidnapped from his home in the Catalonian province of Girona in June by a gang who beat and drugged him before forcing him into a car at gunpoint, according to police.The victim's wife received a telephone call demanding 1.5 million euros in exchange for his being released alive.Police said last week's raid was launched moments before the ransom was due to be handed over to the kidnappers in a car park.
