Street art used to turn youths away from drugs

Known as "Oso" ( "Bear" in English), police officer Oscar Gonzalez uses his passion and art to counter the evil of drugs.

Eye-catching graffiti murals painted by him can be seen on walls and doorways around the capital Bogota to call attention to the social disease of drug abuse.

Since youth, he learned how to use spray paint to turn his thoughts and feelings into works of art, slowly carving his niche among graffiti artists.
