Bogotá, Mar 27, (RHC), -- Colombian police authorities announced Wednesday they had captured Hector Alonso Castro, believed to be the country's largest distributor of synthetic drugs, Xinhua news agency reported.

There were no details as for when or where Alonso was caught. He is accused of several charges including ordering numerous killings.

Hector Alonso Castro, leader of a vast criminal gang known as Los Urabeños, was the main marketer of 2CB, a psychedelic drug commonly known as "pink cocaine," which is highly addictive and sells for about 75 U.S. dollars per dose.

The drug, which was reportedly processed at clandestine laboratories in Cali and towns in Colombia's coffee-growing region, all located in western part of the country, is marketed to adolescents and is turning into a major source of income for the country's criminal rings, officials say.

Colombia's National Police say they had seized 15,890 doses of the drug so far this year.
