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.”
