Essex Police said that a provisional post-mortem examination into the deaths of two hotel guests found in a hotel swimming pool were consistent with drowning.
Police are focusing on the relationship between the victims as part of their investigation.
Chris Falcus, manager of Down Hall Hotel, said:
"We wish to reiterate our condolences to the friends and families of the lady and gentleman concerned.
Both myself and the team at the hotel are deeply upset by what has happened.
The results of the post-mortem examination have concluded that the deaths of the two people were consistent with drowning, which puts an end to inappropriate speculation about our facilities."
