A group of us (8 people) were just walking through a really crowded weekend market on a Saturday morning in Brussels.
After coming out from a crowd and regrouping, a female friend told us her iPhone was stolen. She was probably spotted using it earlier and she had left it in a pocket on her coat which was easy to steal from.
The frustrating thing was that at the first police station, it was closed! We had to spend time to find and get to another police station, and spend time waiting for a report to be filed.
