A man has been arrested over the huge pile of fly-tipped waste dumped in a field in Oxfordshire.
The Environment Agency (EA) said a 39-year-old man from the Guildford area had been held in connection with the pile of rubbish in a field near Kidlington.
The EA previously declared a critical incident over the situation.
Prime Minister Sir Keir Starmer said during Prime Minister's Questions that "all available powers" would be used to make those responsible pay for the clean-up.
The heap, which is up to 150m (490ft) long and 6m (20ft) high, appeared on a field between the River Cherwell and the A34.
