A series of raids conducted across Asia, Africa and Europe resulted in more than 300 arrests and over 600 seizures of assorted wildlife contraband — from several tons of ivory and rhino horns to whale ribs and sea horses, authorities said on Thursday.

Law enforcement agencies from 62 countries took part in the operation codenamed “Cobra III” along with international organisations such as Interpol and Europol, according to a statement released by organisers in Bangkok.

Those arrested in the operation conducted from 4 to 27 May included eight trafficking kingpins identified as three Chinese, four Vietnamese and an Indian, said the statement from Cobra, organised by the Southeast Asian-based Asean Wildlife Enforcement Network, which works with regional officers from wildlife, customs, police and other agencies.

This year’s operation “was the most successful so far,” said police captain Vatanarak Suranartyuth, a senior official with the network. It was the first time that European Union countries participated.

The seizures highlighted the scope of wildlife trafficking:

Over 12 tons of elephant ivory, including 4.3 tons in Thailand that came from the Democratic Republic of Congo and 3.1 tons from Kenya. Other ivory seizures came from Singapore (3.7 tons), Mozambique (1.3 tons) and Uganda (0.6 tons).
