Foreigners, including students, living in Karnataka after expiration of their visa will be identified and deported, said Karnataka Home Minister G Parameshwara on Sunday.

Embassies will be contacted for information about foreigners living in Karnataka past the expiration of their visa, he said. 

The minister's statement comes in the wake of a Sudanese national with an expired visa reportedly killing a local woman on Hesaraghatta Road. The incident was followed by a Tanzanian student reportedly being attacked in the area the same day by a local mob, who allegedly stripped and beat her, sparking protests by African students.

"If their visa period is expired, they cannot live here for not more than a month," The New Indian Express quoted Parameshwara as saying.

The 21-year-old Tanzanian woman was attacked after Mohammad Ahad Ismail, a Sudanese man, reportedly ran over a 35-year-old Indian woman.

Ismail's visa had expired on 31 December, 2015, and he had been told to either renew it or leave the country. However, he had not replied to the police notification, a police source told Deccan Herald.

"We had summoned several students in Soladevanahalli, including Ismail, and told them they were overstaying. We will ask the Acharya Institute of Technology for a list of students who are overstaying," the source said.
