A shopper was left with second-degree burns after her mobile phone exploded in her back pocket.
CCTV footage shows how the device ignited as she chatted to her husband in a supermarket aisle.
Flames billowed from the back pocket of her jeans as she ran about frantically.

Her husband chased her to put the fire out as onlookers watched in shock.
Mateus Soares Lima later told local media how his wife felt heat in her pocket and, before she could react, the mobile phone caught fire.
Her back, bum, hands, and arm were injured, and some of her hair was burned.
Mateus said he took off his T-shirt and smothered the fire with it before running water over his wife’s injuries.
Firefighters arrived at the scene, gave the young woman first aid and took her to a local hospital in Anápolis, north west of Rio de Janeiro, Brazil.
The fire brigade says she sustained first and second-degree burns.
According to Mateus, she will need to undergo a “scraping procedure” on her injuries.
He told local media: “She’s really traumatised. I’m speaking out mainly to raise awareness.
“A lot of people have kids, and this is really dangerous.
“So, it’s important to stay alert, because, just like it happened to her, it could happen to others.”
The woman, who hasn’t been named, purchased the phone – a Motorola Moto E32 – about a year ago.
The device, which was purchased new and directly from the store, hadn’t malfunctioned before, as reported by Need To Know.
A Motorola spokesperson said: “We are already in contact with the customer to look into the details of the incident and carry out a technical analysis of the device, an essential step to determine the cause.
“The company prioritises the safety of its consumers and stresses that all its products are carefully designed and made to the highest standards of quality, undergoing rigorous testing to ensure safe performance for the user.”
