A man from Gloucester has been arrested on suspicion of assault by officers responding to the badger cull.
It happened around 11.30pm last night [Thursday] after a disagreement between two groups in Tirley.
No one was seriously injured.
The 38-year-old remains in police custody.
One of Britain's best-known conservationists is adding his voice to the campaign to stop the culling of badgers in two parts of the West Country later this year.
The Government announced in January the locations for the cull will be in the south west. One is around Exmoor and Taunton Deane area, the other further up the M5 near Tewkesbury and the Forest of Dean. The likely start date for the cull will be August.
Bill Oddie says public opinion has been ignored, and that shooting badgers is not an effective way of preventing the spread of TB in cattle.
Today's protest comes as farmers in the two pilot areas are applying for licences to cull badgers. The trial's aim is not to prove whether there is a link to TB in cattle - the Government says that's already established - but whether shooting is the most effective and humane way of culling badgers.
