All boat operations have been suspended from Bournemouth pier following the death of two swimmers last week, the local council has announced.
A Bournemouth, Christchurch and Poole (BCP) council spokesperson said: “All boat operations from the pier have been suspended as a precaution, pending a conclusion to the police investigation.
“We are aware the investigation is complex and will consult with Dorset Police when the investigation is complete.”
Sunnah Khan, 12, and 17-year-old Joe Abbess died after getting into difficulty in the water on Wednesday, while another eight people were injured.
An inquest opening in Bournemouth on Monday heard that the pair had died of drowning amid a “suggestion” they got caught in a riptide.
A man in his 40s who was “on the water” at the time was arrested on suspicion of manslaughter and was released under investigation on Thursday while police inquiries continue.
Police said Joe and Sunnah were rescued from the sea, but both died later in hospital.
Joe was from Southampton while Sunnah was from Buckinghamshire.
Police said they were keeping an “open mind” about the circumstances that led to the deaths.
