Bolt cutters, a drill and a hacksaw had to be used to free a schoolgirl's tongue from a Disney mug.

Megan Donald, seven, of Kirkintilloch, East Dunbartonshire, was drinking water at school when she realised she could not free her tongue from the Monsters Inc screw-top cup.

Unable to speak, the Harestanes Primary pupil signalled to her teacher before an ambulance was called.

Megan was taken to the Royal Hospital for Children in Glasgow accompanied by mother Natalie following the incident, which happened last Wednesday.

Disney has been forced to take the product of its shelves following the incident.

"When I got to the school I was very alarmed, I wasn't expecting to see what I did," said Natalie.

"I had never seen anything like it before. I thought the mug was stuck at the front of her tongue but it turned out it was halfway down her tongue. Megan was in a lot of pain."

Megan spent about five hours in hospital while staff tried to free her of the mug, which was bought from the Disney Store in Glasgow's St Enoch Centre.

The pupil was given medication to reduce the pain as medics used bolt cutters and a hacksaw to free Megan.

After only being able to smash off part of the mug, staff were forced to use a drill to release the remaining part of the mug.

Ms Donald, 31, said: "They tried to reduce the swelling and then pull it off but it was still stuck on. A variety of tools like bolt cutters and scissors were then used but the plastic was too thick.

"They then started to use a hacksaw which was causing pain because they had to press down on her face so I had to help to reduce the contact.

"The hacksaw got rid of half of it so they then used a dentist drill to free the rest."

Everyone was in shock as the incident left Natalie with swelling and bruising.

She was unable to speak properly for several hours and unable to eat properly for days after being released.

Ms Donald feared her daughter had suffered permanent damage due to the mug.

She said: "My fear was that there would be permanent damage because you need your tongue to speak. We were really concerned about this.

"I have never seen anything like it before. Her tongue was really bruised and swollen. She couldn't really speak and had trouble eating for a few days."

A Disney spokesman confirmed the mugs have been withdrawn from sale as well as three others of a similar design.

He said: "This is undoubtedly an unfortunate incident that we've taken seriously by immediately stopping sales of the mug from our stores and websites and destroying all other existing stock."
