Harrasment is just a jumped up charge by the police, when they can't get anything else.
I change my mind every day if he will be charged or not. Today I think he will probably get a lesser charge like a public order offence and a SHPO.
Agreed that it's a bit of a weird and bizarre trend.
Admittedly with FJM I can guess Cambridge given I can't think of many venues other than the Corn Exchange.
