A historic milestone being restored by the civic body at Dadar West has been found to be damaged, worrying heritage activists. The BMC chief and architects working on it said a deeper crack had led to the breakage and it will be restored to its original glory.

The milestone VII outside Dr Antonio da Silva High School had remained buried under the footpath with only its triangular head sticking out. Heritage enthusiasts had been concerned about it when a blast had occurred a few metres away. The milestone appeared safe then.
