Arrests made over 18mo Melb boy's death

Homicide detectives are investigating the death of an 18-month-old boy in Melbourne's southeast.

A man and a woman were arrested following the death of the child in Langwarrin on Monday.

Emergency services were called to an address in Potts Road about 4.10pm after reports that a child was injured.

Crews worked on the boy but he could not be revived.

Neighbour Craig Blackwell told The Hearld Sun he could hear arguments in the house on Monday afternoon before police arrived.

"She was screaming, shrieking in terror, and the guy in the house was trying to hush her and tell her to be quiet."

Mr Blackwell also said he had conflict with occupants of the house before.

"It's not unusual to hear arguing and screaming," he said.

"I've been over there a bit to tell them to be quiet.

"Last Friday night I was over there at about midnight because of the noise they were making."
