The leg was discovered at around 8 a.m. by a tricycle driver along Bonjack St., South Fairview.
Police believe it belongs to a still unidentified man whose body parts was recovered separately in the last three days in different parts of the city.
Senior Inspector Rey Medina, chief of the General Assignments Section of the Quezon City Police District (QCPD), said Alvin Sajutal was passing through Bonjack street aboard his tricycle when he spotted a black garbage bag.
Sajutal was aghast to discover that the trash bag contained a decomposing leg of a man.
