Closed-circuit video capture the shootout and arrest in South Africa where police obtained nuclear material that could have been used for a dirty bomb.
An international police sting at a Pretoria petrol station has netted four men involved in the sale of a highly radioactive metal suspected to be destined for use in a dirty bomb.
The high-risk operation by the Hawks’ specialised tactical unit was carried out yesterday.
Police recovered some Caesium-137 contained in a protective cover, but admitted they had yet to find a larger device, which was set to be sold on the black market for R45 million.
CCTV footage shows how undercover members of the Hawks’ organised crime unit stormed through a Sasol garage, opening fire on the suspects with semi-automatic weapons, sending terrified customers, motorists and petrol attendants fleeing.
Within moments of arresting the Mamelodi and Vanderbijlpark men, who are aged between 35 and 50, environmental officers and a field team of South African nuclear specialists sealed off the area as they gathered air samples and conducted tests on the radioactive material.
The lunchtime chaos brought an end to a lengthy police investigation involving Interpol agents around the world.
Police said they began their investigation after infiltrating a criminal organisation, which has allegedly been trying to source the highly radioactive Caesium-137.
Sources said the amount recovered, although small, could have been used in building a dirty bomb. According to the Wikipedia website, a dirty bomb combines radioactive material with conventional explosives. It is used to contaminate the area around the explosion and create terror.
A policeman said the source of the Caesium-137 was unknown and investigators were going all out to locate the larger device. “We don’t know what these suspects’ intentions were and we need to find the device quickly,” he said.
Nuclear Energy Corporation of SA spokeswoman, Chantal Janneker, confirmed the material was Caesium-137, and said there had been no contamination in the area.
Hawks spokesman, Colonel Musa Zondi, said the four were arrested as they tried to sell the stolen material which was a sample of a device which was to be sold for R45 million.
Zondi said the suspects would appear in the Pretoria Magistrate’s Court on charges of theft, possession of a radioactive device and violating the Health Department’s prohibition of handling this material in public.

The Pretoria News reported Saturday that police had recovered a limited amount of cesium 137, which has been identified as possible dirty bomb material (see GSN, July 6). The newspaper indicated, though, that the device that once housed the material had not been found.
“At this stage we don’t know where it comes from or where the remainder of the device is, which is of grave concern to us, especially as cesium 137 can be used in dirty bombs,” a police officer said. “We don’t know what these suspects’ intentions were and we need to find the device quickly.”
GSN reported that Friday’s operation was the result of an extended investigation that included Interpol officers from various countries and targeted a criminal group that had spent months trying to sell the radioactive material, police said. It ended at a gas station, with the suspects unsuccessfully trying to flee under semiautomatic fire from the Hawks.
The Right Perspective said in its report officers are still looking for a much larger device the suspects are believed to have.
The Digital Journal reported that Caesium-137 is radioactive isotope (radioisotope) of Caesium and is toxic in even small amounts. It is soluble in water and can be difficult to detect. It is used in small amounts for radiation testing and for some medical applications.
The isotope would make an effective component of a so-called “dirty bomb,” a device which is made up of a normal explosive like TNT and a radioactive isotope. When the bomb explodes, the area it affects becomes contaminated and people coming into contact with surfaces or water containing the radioisotope could become seriously ill or even die.
Caesium-137 was released into the atmosphere during the Chernobyl nuclear power plant meltdown and was one of the three most toxic radioisotopes in the disaster. Dirty bombs are used primarily to created terror in populations, as the explosion itself is no worse than that produced by regular explosives, but the fear of radiation sickness could cause panic.
A policeman who was not named said: “We don’t know what these suspects’ intentions were and we need to find the device quickly” according to the Digital Journal.
The suspects will appear in the Pretoria Magistrate’s Court to face charges of theft, possession of a radioactive device and violation of health regulations pertaining to nuclear material.
The Global Security Network reports that police said the incident was not World Cup related despite earlier reports that Iraq claimed its security forces had detained an al-Qaeda militant suspected of planning to detonate a “dirty bomb” at a soccer stadium.
While it was not immediately clear where the device involved in Friday’s sting had come from, a significant amount of nuclear medicine manufacturing for treatment of certain cancers is manufactured at NECSA’s Pelindaba site near the Hartbeespoortdam outside Pretoria.
In 2007 a daring breach in security occurred at Pelindaba as two separate gangs of armed men broke into NECSA’s operations room during which an official was shot. NECSA passed this incident off as “crime-related” at the time and no further information was ever made available. There has been little fuss in South Africa over the security breach at Pelindaba but international media and nuclear watchdog organisations remain severely disturbed believing that a significant amount of Highly Enriched Uranium at Pelindaba was a likely target for the break-ins.
