The Senior Special Assistant to the President on Foreign Affairs and Diaspora, Abike Dabiri-Erewa said this in a statement by her media aide Mr Abdur-Rahman Balogun on Tuesday in Abuja.
The five suspects who were on visitors visas to Dubai include Chimuanya Ozoh, Benjamin Ajah, Kingsley Ngoka, Tochukwu Alisi and Chile Ndunagu.
According to the police, the men barged into the exchange and smashed the glass barrier between the customers and the staff, stole the money in multiple currencies and fled.
The presidential aide said the action of the five Nigerians is condemnable.
She described the action of the Nigerians in a foreign land as despicable and shameful as it is not in accordance with good character of Nigerians.
Dabiri-Erewa, however, warned Nigerians living abroad to be good ambassadors of the country and desist from tarnishing the good image of Nigeria.
She also advised embassies to screen applicants for visa and ensure that they are of good character
