Beijing - Sniffer dogs began regular patrols for explosives in Beijing's subway stations this week in an anti-terrorism move that was also a preparatory measure for August's Olympic Games there, state media reported Thursday. Police trained 80 dogs, primarily Labrador retrievers and spaniels, for the patrols, which began New Year's Day in one of the most heavily used subway systems in the world.
Sniffer dogs searching for drugs were first deployed in China's capital last summer at airports, train stations and public squares.
Experts said the dogs would have plenty to do in the run-up to the Chinese New Year, which falls on February 7 this year. Fireworks, which often accompany the celebrations, are among the most confiscated items on public transport along with flammable paint and solvents.
Even without the regular canine patrols, police seized more than 700 kilograms of explosive material last year and arrested 499 people.
With China's booming housing market, the number of passengers carrying flammable paints and solvents has risen sharply although the offense carries a five- to 15-day jail term.
The transport of explosives and flammable materials is one of the most frequent cause of accidents in China.
