Travellers were filmed using a digger to break onto a playing field.
The footage shows the digger ripping down a wooden barrier before around 20 vehicles and vans moved onto the field in West Bromwich.
Sandwell Council were able to use the video, filmed by local residents, to persuade the travellers to move - and the group had gone by 10.30pm that evening.
Council officers, police and local councillors joined residents at the playing field on Thursday and the group were ordered to leave or be arrested for criminal damage.
The council has dealt with more than 90 unauthorised encampments with the cost of clean-ups, site security, bailiffs and court costs adding up to more than £250,000 in 2016/17.
