Speaking to reporters on the sidelines of a press conference near the Dabolim international airport, Parrikar said: "It is not racism. If you see earlier history, you will see that more Nigerians are involved in drugs. So people are seeing it that way."
While two village panchayats in Goa have banned renting out houses and rooms to Nigerians students, ruling Bharatiya Janata Party (BJP) legislators have also blasted the Nigerian community living in Goa.
"Nigerians are like cancer," Art and Culture Minister Dayanand Mandrekar said, a day after Nigerians blockaded a major highway protesting against the murder of a compatriot.
Two village panchayats in Goa have banned renting out houses to Nigerians.
Parrikar has said the murder was a fall-out of a gang war between narcotic gangs in Goa.
BJP legislator Subhash Phaldesai described Nigerians involved in Thursday's violence as "wild animals" whose bodies are pumped with drugs.
A day after the violence, an association of rent-a-bike owners have resolved to stop renting out two wheelers to Nigerians.
They also put up banners across the coastal belt in north Goa, which says "No to Nigerians!"
The targetting of Nigerians in Goa has attracted the ire of the Nigerian ambassador to India, Ndubuisi Vitu Amaku.
"Nigerian people are offended that you are more concerned with the welfare of your own people. We are given the impression that the murder of a Nigerian individual is not important to you," Amaku has said.
