KUALA LUMPUR, Dec 6 — The search effort for a missing male teenager who was swept away by strong currents when he and his younger brother, 12, fell into a drain while trying to retrieve a ball in Taman Prima Saujana, Kajang on Thursday has been expanded.

Selangor Fire and Rescue Department assistant operations director Ahmad Mukhlis Mokhtar said the search operation for the 14-year-old victim, from the spot where he was believed to have been swept away downstream, was expanded up to the Sungai Langat junction, covering a four-kilometre radius.
