Colombian ex-policemen arrested on corruption charges

BBC News - Colombian ex-policemen arrested on corruption charges: "Eight former policemen have been arrested in Colombia on suspicion of collaborating with a drug gang.

Officials said they discovered the links when they seized computer memory sticks, which they say contained videos showing the officers being paid off by members of the Rastrojos gang.

The men are reported to have held influential police posts until 2009.

During that time they are accused of allowing the gang free reign in the Valle de Cauca region.

Detectives from Colombia's security police said they spent two years gathering evidence against the eight."
