How to not get sacked for reporting

In 2018 it became common knowledge at the hotel that kids (12-15) were in the toilets most nights, leaving used condoms. Nobody did anything until they were caught by daytime staff and banned. However, the operations manager told the police he had a meeting with the mother of a boy who had been banned, she apparently told him that they live out of town and so would like somewhere for her son and his lover to wait indoors until she picked them up after she finished work. The two children in question though both live closer to their school than the hotel, with the girl also having her mums house within half a mile of the school.  

 
Since the pair were initially banned, the father of the girl has also been seen regularly drinking on the lawns of the hotel in the summertime (despite it being the most expensive place in town and him known for being particularly poor), especially from around school closing time. Since they were caught again by daytime staff, they've not been seen since as the police were called after the boy went mental for being banned again and smashed the hotels front doors window and threatened to knife up staff who had interrupted them in the disabled toilet.  
 
Management were told in 2018 that the girl was the product of a father who was 30 and a girl that was 14, and that there have been allegations of sexual abuse since she was nine, after the father applied for a job at the hotel and he was refused due to being told his history. 
 
In my considerable experience of dealing with cases like this it's possible that the girl is being used by older men too, and the youngsters could ie have filmed their sessions in the toilets for use of their parents to profit from on the Dark Net etc 
 
They have been banned from one other hotel at least, and most other pubs etc have locked disabled toilets, so they have limited access to dry areas, and won't be using their parents houses due to risk of complicity. 
 
After all this, the manager of The Hotel said to those who banned the children  
 
"Always have to get involved don't you!"  
 
then just walked away!! 
 
If you see or hear anything that seems suspicious at The Hotel or anywhere don't hesitate to dial 101 and leave any information you have with the authorities.
