STOCKHOLM, Sweden, May 12 (UPI) -- A former Swedish military commander is being investigated for allegedly trying to hide video footage of naked soldiers shooting shoulder-fired cannons.

Lars-Olof Corneliusson, past commander of the Swedish amphibious military unit stationed outside Stockholm, allegedly ordered the person leading the 2004 nude shooting exercise to demolish footage of the incident, the Swedish News Agency TT reported Monday.

The footage was scrutinized after being aired, against Corneliusson's wishes, by the Uppdrag Granskning television news program in 2006.

Cmdr. Christer Olofsson, who led a military investigation of the incident, criticized the unit for failing to act right away.

Corneliusson is also being investigated for crimes related to a boating accident that left two soldiers dead, the news agency said.
