Mexican 'porn king' arrested

The man allegedly posted websites offering girls to give "services"

A 25-year-old Mexican man is being held on suspicion of being one of the country's biggest promoters of internet child pornography.

Leobardo Diaz Sarabia was arrested in southern Mexico City by officers posing as potential buyers of pornography, the Federal Protective Police said.

He reportedly offered to sell them pornographic images of girls between six and 16 years of age.

Police said Mr Diaz arrived at the meeting with a briefcase containing a portable computer and compact discs with images of children having sex with adults.

The discs were said to be selling for the equivalent of between $145 and $490.

Mr Diaz is also accused of posting websites promising the "service" of under-age girls, and advertisements offering "real sex with girls".
