Hyderabad: At least three persons, all of whom were believed to be dependent on the construction sector for their livelihood, have killed themselves in separate incidents in the Tenali, Guntur and Mangalagiri regions of Andhra Pradesh this month. Their deaths have been linked by many to the slump in activity in the sector caused by a change in the state's policy on sand - which is required in large quantities to help strengthen buildings and used to make both cement and concrete.
