The National Police had already encircled the building in San Pedro Alcántara, when they witnessed the victim falling and then apprehended his captors as they attempted to escape.
Officers from the Guardia Civil and Spain's national tax agency have temporarily shut down the aesthetic center and conducted inspections at five other locations in Malaga province as part of their ongoing investigations.
The assailants reportedly trapped the businessman victim in a secluded location, coerced him into a vehicle, threatened him with a gun, and physically assaulted him.
An examination conducted by the Guardia Civil's Seprona unit has also linked a fourth trainee officer to a plan involving the sale of these fish to wholesalers and restaurants.
Both individuals are sentenced to 17 years in prison for the crime, which was captured by a door camera located across from the building where the attack occurred.
