Just read half of the thread and wondered…the police cannot catch the offenders cause they are too fast and too quick, difficult to ID them, fake plate numbers. So, can local residents help the police? My suggestion is any resident reports the sight of these guys on scooters, one or group - does not matter. We can report on this forum in a dedicated thread. The exact place seen (as specific as possible) and time of the day, how many bikers, as much description as possible. Then a dedicated police officer or officers create a map of those gang sights with time of their appearance which allows the police to predict where and what time those gangs may possibly be. This will give them specific places to have unmarked cars to catch some of them. As in any gang group, there should be leaders - take them down, a group or groups will likely disperse. Also, those gangs communicate via messaging apps or social groups. Having in posession few phones of those moped gangsters will allow to trace most of them. But all residents need to come together to support the police to resolve this issue…if the police will be willing to take this approach.
