KUALA LUMPUR: Police have not ruled out the possibility of more arrests in connection with the illegal dumping that led to toxic pollution of Sungai Kim Kim, Pasir Gudang, Johor.
Inspector-General of Police (IGP) Tan Sri Mohamad Fuzi Harun said they had so far arrested nine men; two in Johor and seven outside the state.
All nine had been remanded for six days since Monday to facilitate the investigation.
"Those arrested were directly involved in the case, but we are still in the midst of identifying the mastermind," Mohamad Fuzi said.
The case is being investigated under Section 278, 284 and 326 of the Penal Code.
Some 3,000 people had been hospitalised in Pasir Gudang after inhaling toxic fumes emitted from chemical waste dumped into Sungai Kim Kim on March 7.
The pollution had forced the closure of 111 schools until the school break.
