The ex-owner of a boat which was impounded after the death of two children in the sea has said the area is "dangerous".
On Wednesday, a 12-year-old girl and 17-year-old boy died in hospital after "getting into difficulties" in the water in Bournemouth.
Emergency services rushed to the scene, where eight other people were treated on the beach after being pulled from the sea by lifeguards.
The young girl was from Buckinghamshire, while the teenager was from Southampton, MailOnline reports.
Pleasure boat the Dorset Belle, which would normally cruise the shoreline of the beach, was impounded by authorities and is now under guard in Poole Harbour, police have confirmed.
The reason why it was impounded isn't known yet, but officials have stated there was no "physical contact between a vessel and any of the swimmers" earlier this week.
Peter Lamb, who used to manage the Dorset Bell for 20 years, said he thinks the sea surrounding the pier was "very dangerous" for swimmers.
The 70-year-old said: "If you swim under the pier then it's very dangerous. There are barnacles around and an aggressive tidal flow and swell."
It is unknown why the Dorset Belle was impounded, but police have said there was no 'physical contact between a vessel and any of the swimmers' on Wednesday.
Mystery still surrounds the tragedy of what happened, with police confirming earlier this week they don't believe anyone had jumped from the pier.
A man in his 40s who was "on the water" at the time has been arrested for the manslaughter of the children.
The two victims suffered 'critical' injuries in the incident that happened next to Bournemouth Pier on one of the hottest days of the year.
During a lunchtime press briefing today, assistant chief constable Rachel Farrell also confirmed the victims were not related and not known to each other.
