In the UK, only police ('sworn constables') have legal protection when conducting an arrest. Ordinary people conducting a 'citizens arrest' are committing a crime if they make a mistake (false imprisonment). Store workers are not usually sworn constables. In any case, the article is not about an arrest. Making someone leave is not an arrest, it's the opposite (an arrest is detaining someone).
