Department of Conservation staff contacted Dunedin police after a couple of members of the public began harassing a sea lion at St Clair Beach yesterday.
Doc coastal Otago operations manager Craig Wilson said staff received a phone call about 12.50pm, from another member of the public who was concerned about the welfare of the sea lion.
"The caller indicated they had tried to intervene but the people became heated.
"Because of this, we contacted police to deal with any potential escalation in tension."
