A Muslim woman was spat at on the street in the aftermath of the terror attacks in Paris.
The man and woman targeted a passerby as she walked along Queensway in Bletchley on Tuesday.
Local Muslims said such violent acts were “not accepted in Islam or society”.
It comes after Islamist gunmen murdered 12 journalists at a French satirical newspaper Charlie Hebdo for drawings depicting the Prophet Muhammad.
Anouar Kassim, director of Milton Keynes Islamic Arts, Heritage and Culture (MKIAC), said: “It shows that sometimes all of us can be tarred with the same brush.
“You can sometimes feel fear.
“MKIAC condemn acts of violence. There is no place in Islam for such acts.
“More integration is needed in our city of Milton Keynes and I have spoken to the leader of the council about this.”
This week, French Prime Minister Manuel Valls said his country is at war with extremism and terrorism, but “not with Muslims”.
On Monday evening, MKIAC unveiled a unity mural at a ceremony at MK College’s Silbury Campus with the High Sheriff of Buckinghamshire, MK Mayor and Bishop of Buckingham.
Mr Kassim added: “This event was so important after what happened in Paris.
“Many Muslim and non-Muslim artists came together and I am grateful for their support.”
