A pair of individuals have been arrested as an element of an probe into the illegal deposit of many thousands of metric tons of refuse in a field in Oxfordshire, England.
Officials stated that a man in his late sixties was arrested at a property in the town of Andover, while a 54-year-old was arrested in Slough in association with the massive pile of waste dumped near Kidlington.
These arrests follow a recent revelation which revealed the operation of in excess of 500 unlawful sites in the country of England, featuring at a minimum of 11 so-called "large-scale sites" greater than 20,000 metric tons.
A spokeswoman for the regulatory agency said that the apprehensions were for ecological and financial offences and constituted a "crucial step" in ongoing inquiries. The apprehended men have been set free on pre-trial release.
The dump in Kidlington, located between the River Cherwell and the A34 highway, is estimated to contain about 21,000 metric tons of rubbish in a mound which is up to 150m (490ft) long and 6m (20ft) high.
This pile of rubbish is made up of what appears to be sorted residential rubbish, chopped up plastic materials, polystyrene, automobile tires and various everyday objects.
It constitutes just a single of 517 unauthorized tips across England, at minimum 11 of which contain in excess of 20,000 tons of waste. These encompass a 280,000-tonne site in Cheshire, two 50,000-tonne areas in Lancashire and Cornwall county and a 36,000-tonne tip in Kent.
The total number of such major sites is probably to be larger, as the environmental body has in the past stated it does not hold data on tonnage for every unauthorized site.
A large proportion of sites are in agricultural areas, often hidden, and on land that should be arable property.
Police state numerous are operated by organised crime gangs, who are making money by demanding far less than licensed firms to accept and bury waste.
Companies have to pay disposal fees to use legitimate landfill sites, contingent on the volume and nature of refuse they are trying to dispose of, and a waste tax is also charged at just over £126 per metric ton.
Initial efforts to clean up the Kidlington area dump commenced earlier this month following worries over the threat of combustion and the effect that would have on the close-by A-road.
A contracted waste clearance firm has been awarded the task to deal with the site over the coming 12 months at a cost of £9.6m.
An enforcement official for the country's environment unit commented that the agency would be seeking to claim back the clearance expenses under asset recovery legislation from any party ultimately prosecuted at the conclusion of its current inquiry.
She noted that this week's apprehensions would help "push the inquiry forward" and enable authorities to "follow more leads to ascertain in detail what happened and who was a party to it".
"This unlawful dump at this location was an atrocious and calculated assault on our natural surroundings and the authorities understand the public's anger at this egregious crime," she said.
A cabinet minister praised the detentions, stating: "This unauthorized dumping of garbage at the site is utterly appalling and has resulted in significant damage to the environment and upset to the surrounding community.
"Our government is committed to stamping out this category of crime across the country, by increasing financing to address environmental crime, hiring more personnel and implementing stricter controls and fines for those who flout the rules."
The apprehensions were executed on a recent Thursday by agents from a dedicated organised crime team and follow an earlier detention of a 39-year-old from the Guildford area region in last November. He was let go subject to more inquiries.
