Kolkata Traffic Police — no proper no entry board was pu

Address:

24/1 BIREN ROY ROAD, BEHALA NATUN PARA, Kolkata, West Bengal, 700034

A lane inside bhawanipur, i took left turn
There was no proper 'no entry' board was put up there. Even after informing that we are new in that road and the no entry board was put on a lap post which was behind a tree in foot path.
They have fined us rs 300 and haven co operated with us.
They were even hiding behind a truck so that no one notice them.
Is this the work of police or traffic guard.
Instead of helping people they are there to give fines where as no proper board was there.
It is a request plz look after this matter, they are just asking for fines instead of doing their duty properly.
If this things are ingnored they will go on behaving in this inhumnan manner.
