Two teenagers suspected of being involved in the website attack on the Serious Organised Crime Agency (SOCA) have been arrested by Norway's National Criminal Investigation Service (NCIS).
The NCIS announced the arrests on Wednesday, confirming it has charged an 18- and 19-year old for suspected involvement in a number of distributed denial of service attacks (DDoS).
"We have arrested the two we think are most important in these attacks, but we still want to talk to more people," said NCIS prosecutor, Erik Moestue.
The agency did not specifically refer to any attack, but speaking to the BBC Moestue added that the attack on SOCA was one it was investigating.
"We know SOCA was recently attacked, as well as Norwegian and American sites, and that is one of the things that we are looking into," he said.
An NCIS spokesperson refused to comment when asked for confirmation by V3.
The Norsk Telegrambyra press agency reported that the country's largest financial services group DNB and its Police Security Service have been affected.
At the time of publishing neither organisation had responded to V3's request for clarification while SOCA said it had no comment to make.
If found guilty of the offence under Norwegian law the two could face a maximum six year jail sentence.
No further details were given regarding the two youths' identities or group affiliations, though F-Secure analyst Sean Sullivan said he thought it unlikely they are affiliated to a the hacktivist Anonymous collective.
"Doesn't really sound like Anonymous or copycats to us. It also doesn't seem to have been for the 'lulz' based on the current information," Sullivan told V3.
DDoS attacks are a pressing concern for companies, with hacktivist groups like Anonymous regularly using the tactic.
