Police have recorded statements from the grandmother and parents of the three-year-old boy who died at his home in Semenyih near here on Thursday.

Kajang ACP Ab Rashid Ab Wahab told Bernama the statements were recorded last night to facilitate investigations under Section 31 (1) Child Act 2001.

"Police also quizzed the in-laws of the boy's father today.

"We also recorded statements from the two policemen who went to the boy's house to investigate the case after a report was received on the boy's death," he said.
