The woman claims it took half an hour for a police dog unit to arrive on the scene, who then told the group there was 'nothing they could do', because 'all their resources were in central London.'

'One of the students is the daughter of a Polish diplomat. She was put in a situation where she was unsafe.'

I wonder what would have happened if they'd tried this in Poland, with Polish police?
