Ghaziabad Development Authority [GDA] — illegal encroachment in park

Address:

Ghaziabad, Uttar Pradesh, 201010

I have a complain regarding green belt/park adjoining to surya kanishk tower in sector-4, vaishali, ghazabad -201010 on the service lane to vaishali metro and adjoining to mahaluxmi metro tower.
Geen belt/park mentioned above is captured by influential person and their intention to capture it permanently. Construction material and debris already placed three. I think within 2-3 days, green belt will lost and concrete structure will be there.
These person does not afraid as they already capture some part of street by putting vendors and kiosks one after another since last year.
I across daily from that road and see they gradually capture the public place/street/ green belt.
I can't disclose my identity but being a conscious citizen, it's my duty to inform the incidence.
