On May 25, a Nigerian student in Hyderabad was allegedly beaten by an Indian over a parking dispute, while on May 28, four separate cases of alleged assault on Africans in the national capital were reported.
The former beauty queen expressed her concern on Twitter.
"The recent incidents against Africans in Delhi are a matter of shame for us as a society, but also a test of our law and order machinery," Gul tweeted on Tuesday.
"Let's not forget what our founding fathers said in the Constitution. The Indian state will battle and reform society's worst impulses," added Gul, who was an Aam Aadmi Party candidate from Chandigarh during 2014 Lok Sabha elections.
