Owen Road fire: Maid asked to take lie detector test
She is believed to be last person to see employer alive
A key witness in a fire incident has been asked by the police to undergo a polygraph lie detector test.
The Sri Lankan maid, known only as Rani, is believed to be the last person to see her employer, Madam P. Lakshmi, alive before the Owen Road flat they lived in was engulfed in flames on Wednesday.
Family members of the 92-year-old victim told The Straits Times last night that Rani had been asked by police investigators to take the test.
A polygraph measures a person's breathing rate, pulse rate, blood pressure and galvanic skin reflex, to determine if he or she is lying.
