STOCKHOLM (AP) — Swedish authorities say a TV tower that snapped in half may have been the target of sabotage.

The top portion of the 330-meter (1,080-foot) mast near Boras in southwestern Sweden broke off late Sunday and slammed into the surrounding pine forest. No one was injured but TV and radio transmissions in the area were knocked out.

Swedish prosecutors said Wednesday they are investigating the incident as suspected sabotage but said they have no suspects at this point.

Security has been stepped up at other TV towers around the Scandinavian country.

Tower operator Teracom said it was the first time a TV mast had snapped in Sweden since the 1980s.
