A woman who became trapped in remote marshland saved herself by using the torch app on her mobile phone to summon help.

Emily Cox, 24, suffered a badly sprained ankle while walking her father’s dog by herself in the New Forest.

She was unable to get up and free herself from the boggy ground and, with light fading, called dad Julian Cox on her mobile.

He was able to pinpoint her position using the Life 360 app and drove from his home in Bournemouth, Dorset, to her location near Picket Post, near Ringwood.

Julian arrived 15 minutes later, parked his car and looked across the darkened landscape to see a flash of light in the distance.

He walked through waist-deep mud and water to get to Emily but was unable to rescue her.

Fire crews from Ringwood, Poole and Ferndown were called and used specialist equipment to reach the injured 24-year-old.

She was rescued at about 7.30pm on Friday, three and a half hours after she suffered the accident.

Emily was warmed up and assessed by ambulance paramedics at the scene and it was confirmed she suffered a badly sprained ankle but didn’t need hospital treatment.

Her father said: ‘When Emily called me it was getting dark and she was trapped in the middle of marshland.

‘Luckily we use the Life360 app and I was able to see exactly where she was.. I jumped in the car and got to the Picket Post car park 15 minutes later.

‘I looked right across the valley which was dark and I could see her phone torch on.

‘I went to her while on the phone to the emergency services and was wading through waist-deep water.

‘The fire brigade and the ambulance service were there very quickly – I can’t praise them too highly.

‘One of the firefighters was up to his chest in boggy wasteland.

‘It was very dark, very cold and very wet.

‘It was a very scary experience but luckily she had her mobile phone with her.’
