Emergency services were scrambled to Billing Aquadrome in Northamptonshire when it was feared people could be trapped in a car submerged in a lake.
Paramedics, police officers and a fire and rescue crew were also called to the Northamptonshire holiday spot at 1.30am yesterday (August 13) but a search revealed no one was in the car once it had been hauled out of the water, and no one could be found in the surrounding area.
The East Midlands Ambulance Service (EMAS) scrambled its Hazardous Area Response Team (HART) after the call at 1.19am from a member of the public.
A spokeswoman for EMAS said: “The caller stated a vehicle was face down in the water and they believed a person was inside.
“Given that the incident appeared to be a water rescue our HART team were called to provide support.
“The last update we have is that no patient was found, so no one was treated or transported.”
A police spokeswoman said officers carried out a search of the area, but no one was found.
She said the force was trying to trace the owner of the Peugeot make car and could not speculate how the vehicle ended up in the lake at this stage.
Billing Aquadrome has been contacted for a comment.
