Environment Agency (EA) enforcement teams in the East Midlands have started to wear video cameras following a successful six-month trial in the north-east.
The trial found that wearing cameras helped to reduce incidents of anti-social behaviour, assaults and threats against EA staff, following a growing number of abusive incidents during inspections to waste sites.
Officers will also use the bodycams for fisheries enforcement.
The EA said footage captured on a bodycam in the north-east was recently used for the first time to convict an offender, who pleaded guilty to wilfully obstructing officers and using abusive behaviour towards them once he knew they had video evidence.
Defendants were less likely to challenge evidence when they knew it had been captured on video.
Pete Haslock, EA enforcement team leader for the East Midlands, said: “The safety of our staff is paramount. They are well trained in dealing with hostile situations and we take any threat against them very seriously.”
