Melbourne, June 9 : Indian groups standing guard at railway stations in Melbourne's west to protect students from racial attacks, have been asked to move by the police.

The groups have been gathering at St Albans and Thomastown railway stations after a spate of assaults on Indians in the area, the latest on Kamal Jit, 23, who was bashed unconscious while walking home from the St Albans railway station on the weekend.

A Victoria Police spokeswoman said police had already increased patrols on the Sydenham train line, the railway stations and at St Albans shopping centre, The Age reports.

She said Indians conducting their own security patrols should "leave and let police do their jobs."

"We have been talking to them about their concerns and because of that have increased patrols in the area," the spokeswoman said.

The group has complied with police requests to move, but then returned the following night or gone to other locations, she added.

She refused to confirm whether two men who stabbed a 20-year-old man in St Albans yesterday were Indians lashing out after being racially abused by the victim.

No one has yet been charged over the incident. (ANI)
