A British influencer arrested in Miami on suspicion of aggravated assault with a deadly weapon has complained that US police and jails are far harsher than those in the UK following his release. 

Wolfi Watson, 20, from Bury St Edmunds, Suffolk, is better known online as Costakid and had been filming pranks and social media content in Florida.

The 20-year-old Briton was arrested last week, with bail set at $5,000, according to official records, spending five days in Miami-Dade county jail.

Watson has amassed more than 300,000 followers on TikTok and 116,000 on Instagram, gaining a reputation for daring pranks, sometimes on police.

Following his release from jail last night, he posted a video on Instagram in which he complained that he had not showered for almost a week and had struggled to go to the toilet.

Costakid also claimed he was threatened by prison officers after asking to use a TV remote, suggesting that US prisons and police are far tougher on inmates than those in Britain.

'First day out. Nothing like UK jails. Let me tell you something, the police here don't play,' he said.

'I asked if I could change the channel on the TV and an officer said he was going to punch me.

'I haven't showered. I haven't s**t in like five days. Oh my days'.

Watson did not address the alleged deadly weapon incident in his social media monologue.

However, he added: 'I'm not drinking alcohol again.'

His TikTok and Instagram accounts are packed with challenges, pranks and collaborations with other influencers.

He is originally from the largely affluent Suffolk market town of Bury St Edmunds, which he still refers to as his 'hometown'.

Watson also filmed content in nearby Ipswich and Norwich before later moving on to London, where a number of videos appeared to show him being arrested outside a pub by armed police following a prank call.

In another he was held again by armed officers in what appears to have been Leicester Square. 

The stunt is known as 'swatting', in which a false report of a serious emergency is made to authorities, prompting the deployment of police with guns.

In recent weeks, Watson has shared a string of clips from Miami.

While in Florida, he posted videos of himself flirting with local women, searching for alligators.

He also claimed that he and a friend had come under gunfire after attending a party.

One video uploaded to his account purported to show a bullet hole in the door of the vehicle in which he was travelling.
