This is good advice, seriously!
I have worked at an airport and have spoken to a security officer who helped a woman stop being transported and killed.
The woman did not know she wasn’t going to be coming home, until she got to the airport and her husband went to the toilet and she realised only he had a return ticket.
She somehow managed to quickly think to hide her bangle so that she could set the metal detector off and have to be searched. As the officer was up close and searching her, the woman whispered “help me”. The officer quickly took her for a private search, grabbed the woman’s bags and passport too ‘as protocol’ and went into the private search room. The woman fell on the floor crying, begging for help, so they called the police. The husband started to get suspicious and tried to break his way into the room and the officer had to push against the door, thankfully the police turned up straight away and restrained him. He was arrested and she was given protection and moved to a new city to start a new life. It was harrowing to hear, and really awful to know that this goes on!
If you have any suspicion of something like this happening, even an inkling, please do something, call someone.
