The haul in Calpe is one of the biggest ever made in Spain A National Police operation has seized more than 160,000 fake Viagra pills, one of the biggest hauls ever made in Spain. They are reported by Europa Press to have come from India and China, and were seized in the course of three property searches which took place in the town. Officers also found 15 kilos of benzylpiperazine, a synthetic recreational drug which is known as BZP and which has effects similar to those produced by amphetamines. Five suspects were taken into custody and will now face charges from the courts.
