Builder blocking common passage can i remove the gate blocking it

I have an inherited property which has 50% built up area and 50% area has Chawl type construction having one tenant. The Chawl has 3 exit doors and 3 windows opening towards a "common passage" being used from my father's days (Around more than 50 years). On the other side of the "common passage" is also chawl having rentals by many. All have been using the same "common passage" to reach to the front road for the same period. Recently a Builder has purchased whole area and yesterday has blocked the "common passage". I have alternative exit to the front road but I cannot use the "common passage" exit since yesterday. My tenant has sole exit route through "common passage". However on measurement it is possible that the builder may claim up-to my wall parallel to "common passage".Meanwhile the builder has allowed an alternative passage but that passage has no legal standing. The builder may block the alternative passage whenever he starts property development.Can I remove the blocked gate?
