Police arrested employees who provided workers with accomodation likened to 'holiday camp'

Police arrested the employees of people they believed were slaves instead of assessing the situation to see if any criminal offences had been committed, they swooped and arrested the employers. Did they fail to spot nearly 200 workers freely pottering about, provided with clean heated caravans and use of a recreation room, including free wifi, pool tables, oh and there was a swimming pool!!! How much did this raid cost the tax payer? http://www.telegraph.co.uk/news/2018/02/09/not-slaves-100-migrant-workers-say-launch-protest-arrest-farm/
