UPDATE 4.16pm: THE father of Gurshan Singh Channa says there was no bad blood between him and his son's accused killer.

Speaking through a translator this afternoon, Harjit Singh Channa said he and his son’s accused killer weren’t enemies.

“There were no old frictions in the families,” Mr Channa said.

The family of Gurshan Singh Channa spoke of their shock today after a housemate was charged in relation to the three-year-old's death, as police denied reports from India that further arrests had been made.

Media reports in India claimed the wife of a 23-year-old Gursewak Dhillon had been arrested after the man was charged with manslaughter by criminal negligence over the death.

The Press Trust of India news agency reported that Mr Dhillon's wife "was likely to be charged with helping her husband in disposing of the body'' after she was also placed under arrest.

But Victoria Police said emphatically today this was not the case.

"Definitely not. The wife has not been arrested or charged,'' a police spokeswoman told AAP.

She added that no further arrests or charges over the three-year-old boy's death are expected at this time.

Mr Dhillon appeared in an out-of-sessions court hearing last night charged with manslaughter by criminal negligence.

Raman Deep Singh, a cousin of Gurshan's father Harjit, said they were all shocked Mr Dhillon was charged.

"This is our friend, not a close friend, but we know the person, it is a shock, (we are) shocked man," he said.

Police say Gurshan Singh died after being driven around suburban Melbourne in the boot of a car, unconscious, before being left where his body was found.

Homicide squad Det Sen-Sgt Ron Iddles said Mr Dhillon put Gurshan in a car unconscious last Thursday, but had believed he was still alive.

Det Sen-Sgt Iddles alleged Mr Dhillon drove for three hours with the child in the boot of the car before stopping at Oaklands Junction, in Melbourne's northern suburbs, and placing him in grass.

Mr Dhillon is accused of not checking if the child was still alive and returning to the David St, Lalor, house where he lived with the boy, his parents, and several others.

Det Sen-Sgt Iddles said Mr Dhillon, a married part-time taxi driver, still had an immigration matter which was under investigation and had no strong ties to Australia.

"I believe at this stage he is an unacceptable risk'' for bail, he said.

In seeking bail, Mr Dhillon, who is on a student visa having moved here two years ago, said he intended to start work this Wednesday as a courier.

Det Sen-Sgt Iddles said that if bailed, Mr Dhillon could not return to David St because "it would be an untenable situation for the accused to be living with witnesses''.

Bail justice Ben Czerniewicz said he was running out of options and remanded Mr Dhillon to appear at Melbourne Magistrates' Court tomorrow, saying he agreed with police that he was an unacceptable risk.

Gurshan's parents earlier spoke to detectives and attended a prayer service at a Sikh temple at Craigieburn.

Mr Singh said the family were grateful for the show of support.

"We are very thankful to Indian community, Punjabi community and Australian people,'' he said. "They all are coming forward to help us.''

A car suspected of being in the area where Gurshan, 3, was found near Melbourne Airport emerged as a focus of the investigation.

Police want to talk to anyone who saw a green VR or VT Holden Commodore.
