The boutique owned by The Only Way Is Essex star Lydia Bright was vandalised on Friday evening, with the alleged culprit being caught after a dramatic chase.
Fashion blogger Lydia was apparently in the shop in Loughton High Street when the window was smashed.
The Sun quoted shop worker Katie Corcoran saying: "It was very frightening. The noise of shattering glass. I've never heard anything like it.
"I don't know if he was showing off or he was doing it to spite Lydia. No-one knows. I just saw him do it then he ran off and everyone went after him.
"He was a bit, 'Oh, I’m sorry' when he turned up to the shop. He couldn't run anymore because there were so many people chasing him. I think he just gave up and thought, 'I'm just going to go with it'."
The vandal was reportedly chased by members of a film crew who were working in the shop.
Lydia later tweeted: ""Unfortunately today Bella Sorella was vandalised. The suspect is in custody & the issue is being resolved. Open tomorrow as usual x."
And Essex Police issued a statement saying: "An 18-year-old man was arrested for criminal damage and received a caution."
