The South African police on Sunday announced it seized more than 15 kg of cocaine in a routine border check.

A man aged 36 attempted to smuggle cocaine from South Africa into a neighboring country, but was stopped at the Beit Bridge border post in the northeastern province of Limpopo, said police in a statement.

A police officer at the border post was conducting a routine check on the suspect's bag, when he found the rollers with yarn inside the bag was exceptionally heavy. The officer then used a sniffer dog and uncovered small plastic bags containing cocaine.

The cocaine weighed 10.8 kg, with an estimated market value of 12 million rands (about one million U.S.dollars), said police.

The search led to another bust of more than 5 kg cocaine hidden inside a false compartment in the bag."It was worth over 6 million rands," police said.

The suspect will appear in court on Monday, facing charges of the drug possession and smuggling.

It was the latest victory for the South African police to combat the drug smuggling this year.

On March 8, a South African aircrew member was arrested in Johannesburg for allegedly drug trafficking from Brazil into the country.

According to a report of the UN Office on Drugs and Crime in January 2012, South Africa had become an important transit point of drug trafficking routes in the southern African region.
