Days after the latest assault on Indians in Melbourne, India on Wednesday told Australia to take immediate steps to punish the guilty.

“We are concerned about recurring attacks on Indians in Australia,” external affairs ministry spokesperson Vishnu Prakash said. Two Indians and two other people of Indian origin were assaulted in Melbourne on Sunday.

India’s high commissioner to Australia Sujatha Singh took up the issue with Australian foreign minister Stephen Smith. She also wrote to Victoria premier John Brumby, expressing concern about the attack. Brumby, who will visit India next week, condemned the incident.
