Anna Burns, the Environment Agency’s area director for The Thames, said: “The appalling illegal waste dump in Kidlington has rightly provoked outrage over the potential consequences for the community and environment.
“We have been working round the clock with the South East Regional Organised Crime Unit to bring the perpetrators to justice and make them pay for this offence.
“Our investigative efforts have secured an arrest today, which will be the first step in delivering justice for residents and punishing those responsible.”
The agency has said it is conducting a major investigation and coordinating with Oxfordshire County Council, Thames Valley Police, and National Highways.
In a statement, the Environment Agency said: “After officers became aware of continued criminal activity on site in October, a court order was sought and granted to close the site.
“Since this was granted on 23 October, no further tipping has taken place.
“For both safety reasons and because the site is now a live crime scene, members of the public should avoid entering the site.”
