The Rachakonda police today cracked the case of the theft which took place at Nacharam by arresting two natives of Nepal.
The accused have been identified as Arjun and Maya, and are reportedly members of a Nepali gang.
They joined as domestic servants in the house of Nacharam resident Pradeep Kumar 15 days back by claiming to be a couple.
On October 19, they injected a tranquilizer into the 70-year-old mother of Pradeep after finding her alone in the house, and decamped with 19 tolas of gold and a wristwatch.
Pradeep approached the Nacharam police, who registered a case against the two and traced them.
Rachakonda Police Commissioner Mahesh Bhagwat produced the two accused before the media after their arrest.
