External Affairs Minister Sushma Swaraj on Thursday assured an impartial probe into the alleged racial attack on some Nigerian students in Uttar Pradesh and promised action against the guilty.

"The moment I got information about the attack, I immediately sought a report from the Uttar Pradesh government. I also talked to Chief Minister Aditya Nath Yogi and asked him for a public assurance of an impartial probe into the matter," Swaraj informed the Rajya Sabha.

She said that Aditya Nath has assured of an impartial probe into the Monday night attack on four Nigerian students by a crowd in Greater Noida, some 40 km from the national capital.

The mob targeted the African nationals blaming them for drug running following the death of a teen due to suspected drug overdose.  

"Unless the probe is complete, it will not be appropriate for me to say anything on the matter," added Swaraj, after Janata Dal-United member Sharad Yadav raised the matter in Rajya Sabha.

"The (UP) administration there is ensuring peace and security as well as treatment of the injured Nigerian students. I assure the Parliament, there will be an impartial probe and action will be taken against whoever found guilty," she said.
