Three men have been arrested on suspicion of murder in connection with a missing person case in Poole, Dorset, England. The arrests follow reports that a man went overboard from a sailing boat in the area of Arne Bay between 8pm and 9pm on Friday. The missing individual, whose identity has not been disclosed, has not been located since the incident. Dorset Police received the report of the man going into the water at 6:56pm on Sunday, prompting an investigation into the circumstances surrounding the disappearance and the delayed reporting.

Forensic officers have been examining a nearby block of flats at Baiter Park as part of the ongoing investigation.
