Something similar happened to me in Dublin about 5 years ago. After leaving an escort two guards stopped me and was questioned in their car. They took my details and I was told, I had never bothered again. Three years later I got phone call from one of the sergeant and they ordered me to attend as a witness on a trial. Thanks God, the trial was cancelled.
I presume, they may cite you as a witness.

Could you please pm me the detail of that girl? Thanks
