Police released several gas canisters into a house where Groves was believed to be hiding, and then found him hiding in a crawl space, CBS News, BBC's US partner, reported.

The men worked out how to build constructions with large spaces between the molecules, through which gases and other chemicals can flow.

Vera first ordered restrictions in July on the use of 40mm projectile launchers, tear gas, stun grenades and other crowd control weapons at street protests.

"There are times I've had to have a gas mask on inside my own home," she says, demonstrating how she now wears her mask to sleep.

A government spokesperson said the chemicals industry was paying the fossil fuel penalty, with wholesale gas costs remaining 75% above their levels before Russia invaded Ukraine.
