Fire crews used a special app to trace a teenager who had got stuck in the mud at a popular park.

The 13-year-old was in distress after she got trapped with mud coming up to her chest.

Firefighters managed to pull her to safety after locating her through the what3words app.

The girl got into difficulties at Leverhulme Park on Sunday afternoon.

Six appliances were sent to the scene and were there for around 40 minutes.

The youngster was assessed for hyperthermia by the North West Ambulance Service but was later taken home.

A fire service spokesperson said the what3words app was useful in locating the girl.

They said: "As Leverhulme Park is so vast we did not have a location.

"What the crew did was they got one of the kids with the girl to download what3words.

"When you get it it gives you three words that locate you to within three metres.

"That is how we found her."
