Arrest made in connection with Indian student's death

A 15-year-old boy has been arrested in connection with the killing of Indian student Nitin Garg in Melbourne, which police say was not racially motivated.

The teenager was arrested on Thursday morning at Yarraville and was due to appear in a children's court charged with murder.

Detective Inspector Bernie Edwards says a murder weapon still has not been found.

"A 15-year-old boy has been spoken to and he will be charged," Det Insp Edwards said.

"We are extremely pleased for Nitin Garg's family and the Indian community here in Australia."

Det Insp Edwards said police are continuing to talk to other people about the killing but would not say if further charges are expected.

"In our inquiries at this stage we don't believe it was racially motivated," he told reporters.

He also said there was no evidence of a gang involvement in the death of Mr Garg, who was fatally stabbed while he walked through a West Footscray park on his way to his job at a Hungry Jacks fast food restaurant on January 2.

"It's relatively clear why it happened and how it happened but I won't speculate on the motive," he added.

He admitted that homicide detectives had felt the pressure on solving the murder after the Indian government had claimed it was racially motivated.

"Like any homicide we will keep going until we solve it, however there was a lot of pressure and I congratulate Senior Sergeant Dave Snare and his team in their investigation," Det Insp Edwards said.

He said 15 detectives were involved in the investigation.
