The Smithy Family has offered a £5,000 reward for information following a devastating fire at their home.

The TikTok stars, who have 2.5m followers, have been left "devastated" after their house was destroyed by the fire.

Dad Nick and mum Jess were forced to grab their two young daughters Amelia, 6, and Isabella, 9 and a newborn baby boy when they realised their car was on fire at around 10pm on Wednesday.

In a desperate appeal, dad Nick Smith, 33, pleaded for help tracking down the culprits behind the senseless act.

In a video shared on the family's TikTok account on Saturday, he said his wife and kids will only feel safe once those behind the attack are locked up.

The reward, offered by Jess’ mum, is for any information given to the police that leads to an arrest.

Nick said: “Jess’s mum has put a £5000 reward for any information given to the police leading to the arrest of the two people that committed the crime or someone who may have organised it.

"If anyone knows anything please let's make sure no one else goes through this again and help us feel safe again.

“At the minute we’re looking over our shoulder thinking who is that, who’s done this.

“Jess doesn’t feel safe and nor do the kids and to be honest, quite frankly, nor do I.

“So if anyone can help us begin to feel a little bit safer again and you have information, please give it to the police and help find the person that did this.

“As I said there’s a £5,000 reward. Thanks for listening.”

A spokesperson said: "We were called to reports of a car alight that had spread up the outside of the house.

"There were a number of mobility scooters parked outside which had caught alight and were producing a large amount of smoke and flames.

"Everyone was out of the building before we arrived, and crews worked incredibly hard to prevent further damage to the inside of the property and to neighbouring properties."

The Smithy Family's TikTok videos began with dad Nick posting pranks and sketches of family life in lockdown which helped them clock up a staggering 268 million 'likes'.
