Britain's National Crime Agency has arrested two people in relation to the ransomware attack on police surveillance cameras in Washington DC, reports The Washington Post.

The two, arrested in London, were identified by the British media as a British man and Swedish woman. Both are currently out on bail while officials continue to investigate the hack, which took place days ahead of Donald Trump's inauguration.

The attack came through ransomware and targeted DC's surveillance camera system between Jan. 12 and Jan. 15. As a result, 123 of 187 network video recorders were rendered non-functional. No ransom was paid by the authorities, who said it could be a localized extortion bid.
