Several witnesses at the youth camp, believe (as of 23 July 2011) that there was more than one shooter. The police have received descriptions of a second gunman, and are currently checking this information. Due to the uncertainty surrounding these witness descriptions and the chaotic nature of the events the police have, as a matter of precaution, yet to make an official comment on the matter. Acting Police Chief Sveinung Sponheim has said that "It's very difficult at this point to say whether he was acting alone or whether he was acting as part of a larger network".
