Photos: A dead tuna in Sliema

A dead tuna fish has been found in Qui Si Sana, Sliema.

A reader sent these photos at around 8pm, and said that there are people swimming in the area.

She went on to say that there are no fishermen in the vicinity.

Earlier this week, the Environmental Health Directorate issued a precautionary warning that advised against swimming in Qui-Si-Sana due to a discharge of water from an unknown source onto the rocks and sea.
