Perturbed over constant harassment by a stalker, an 18-year-old girl committed suicide at Annarigudem in Thallada mandal on Thursday night.

Agitated over the death of the girl, villagers staged a demonstration in the mandal headquarters on Friday morning, demanding deterrent action against the “stalker.”

S. Renuka, 18, a farm labourer, consumed pesticide at her house. She was rushed to a private hospital at Wyra where she died.

Grief-stricken relatives of the girl alleged that D. Chandar Rao, 20, of the same village used to pester her to marry him. The Thallada police registered a case against Chandar and are on the lookout for him.
