The UK Metropolitan Police Central e-Crime Unit made two arrests earlier this month for suspected use of the Zeus Trojan.
A man and a woman, both 20, were apprehended in Manchester on 3 November in Europe's first arrests with regard to Zeus, according to a Met Police statement on Wednesday.
A Met Police spokesperson told ZDNet UK on Thursday that a man and a woman had been arrested for suspected criminal distribution of the Trojan, which is also known as Zbot.
The two have not yet been formally charged, said the spokesperson, who added that they have been given police bail while the investigation continues.
