Persatuan Hindraf Malaysia (PHM) has accused the police of being sluggish in probing the attempted suicide of a 14-year-old Indian boy at the centre of a religious tussle  in Negeri Sembilan.

G Thiyaggurudeen drank the herbicide paraquat on March 11, claiming mental trauma caused by his school teachers and Negeri Sembilan Islamic Affairs Department (Jains) officers.

The teen, who is registered as Muslim, claimed he had been detained by the teachers and Jains officers at an Islamic missionary centre on Feb 13.

He claimed certain parties later forced him to lodge a police report against his Hindu father.

The father, S Ganesan, has since lodged multiple police reports on the matter and has also been questioned by Bukit Aman and Port Dickson police.

Hindraf chairperson P Waythamoorthy ( right ) however claims police have yet to call in and question the teachers and Islamic Affairs Department officers involved.

"Are the police waiting for the boy to lose his life first before initiating a sham investigation?" he asked in a statement Wednesday.

He also accused them of being racially prejudiced and wants Home Minister Ahmad Zahid Hamidi to intervene in the matter.

Paraquat still present

Malaysiakini 's attempts at finding out the progress of police investigations have so far been unsuccessful.

The Negeri Sembilan education department has also refused to comment on the matter, citing the police investigation as the reason.

When contacted, Ganesan told Malaysiakini that doctors at Seremban's Tuanku Jaafar hospital - where Thiyaggurudeen is being warded - still cannot give a definitive answer as to his son's condition.

"The (latest) results have not come in yet [..] but he can still talk and eat," he said.

Ganesan revealed that earlier tests showed Thiyaggurudeen's kidneys and urine are still showing positive for paraquat.

The herbicide can cause multiple organ failure even in small doses and takes several days after ingestion before it can be detected in the body.
