Woman ends life
A 25-year-old doctor committed suicide by hanging at her house in Sathasivanagar on Monday night. Police said R.Vijayalakshmi, a native of Chennai, was working in an ayurvedic centre near Anna Nagar. She had called some friends and told them about her plan to commit suicide.
When a hospital employee went in search of her, there was no response from her house and the door was locked from inside. When the police broke open the house, Vijayalakshmi was found hanging.
Silaiman Inspector T.Balamurugan said the girl was said to have opposed the marriage plan proposed by her parents. It could be a reason for her taking the extreme step. Investigation was under way, he said.
