Police are warning the public against swimming in Darling Harbour after a man had to be pulled from the water.
About 9.45pm on Saturday police discovered the man swimming at Cockle Bay, and had to pull him from the water when he ignored their instructions to leave the water.
The 37-year-old man was charged with swim or paddle in waters of Cockle Bay without authority, obstructing or failing to obey directions of rangers or staff, resist or hinder police in the execution of their duty, and offensive conduct.
Sydney City Duty Officer Inspector John Bamford reminded the community that is unsafe to enter the water in Darling Harbour.
"Swimming in Darling Harbour puts you at risk of oncoming boats and vessels and sharks in the water," he said.
