Drum lines investigation

The Department of Fisheries is investigating the sabotage of baited drum lines off Cottesloe beach this week.

Fisheries officers had to repair several of the lines, which are set 1km offshore to catch and kill large sharks under the State Government's controversial policy, on Wednesday morning after someone removed the hooks and tied the drum lines together with a rope overnight. A spokeswoman for Fisheries Minister Ken Baston said the department was working with relevant agencies on its investigation. She said no further damage had been reported.
