The police department in federal actually implemented this thing by placing a secret bell as the Capital consists migrants from all over the country and usually on occasions like Eid the Capital is mostly SILENT all over with the urban culture where people are not much concerned of their neighbors and they dont try to interfere in any matters as such.
This secret bell Rings to the adjacent neighbors giving them the Alarm signal that their is something fishy in our neighborhood and they can give a call to 15 or local police station.
