Fight over the precious red-sandalwood has been on for years in Andhra Pradesh and Telangana. Several police officials have lost their lives in trying to prevent such illegal activities.

In one such encounter, twenty red-sandalwood smugglers were shot dead by task forces at around 5:00 am on Tuesday morning in the Seschalam forests near Tirupati in Chittoor, Andhra Pradesh.
