Britain’s FBI has seized £10m worth of shares in a luxury watch shop as part of a money laundering investigation.

Britain’s FBI seized £10million worth of shares during an alleged money laundering probe at a luxury watch shop whose customers include Premier League footballers and rapper Stormzy.

The National Crime Agency (NCA) seized more than 300 WatchTrader & Co watches last year in a surveillance operation that led to four arrests.

Newcastle-based WatchTrader & Co allegedly traded timepieces on behalf of clients, who were then paid after the watches were sold, The Sun reported.

Those who claim to own one of the confiscated watches must now file a tax return to prove they had “legitimate means” to purchase the designer pieces.

The National Crime Agency (NCA) seized more than 300 WatchTrader & Co watches last year in a surveillance operation that led to four arrests

The NCA seized hundreds of watches – including those from Rolex, Patek Philippe and Audemars Piguet – from the Jesmond, Newcastle shop last October.

Since the seizure, customers have reportedly been trying to reclaim their watches – some of which are worth up to £300,000 each.

A customer allegedly had six watches that investigators were selling at the store. Her collection is said to be worth more than £1million.

Another customer told The Sun he was “frustrated” with the NCA because they “refused” to return his £60,000 Rolex even though he provided the receipt.

The agency reportedly sent him an email stating: “The NCA continues to lawfully detain watches seized in connection with suspected crime.

“The release will be considered on a case-by-case basis.”

MailOnline has been contacted by WatchTrader & Co and the NCA for comment.

WatchTrader & Co is said to be cooperating with the NCA investigation and “continuing to trade normally”.

The company has sold timepieces to the likes of England players Alan Shearer, Callum Wilson and Conor Coady, as well as Newcastle United’s Allan Saint-Maximin (pictured in store).

The company has sold watches to English players Alan Shearer, Callum Wilson and Conor Coady, as well as Newcastle United’s Allan Saint-Maximin, among others.

Manchester United’s Lisandro Martinez was also spotted in the store just five days before the seizures.

A source told the Sun the investigation is a “huge headache” for footballers, who “love” high-end watches because they’re the “ultimate status symbol in the dressing room.”

“The guys may now have to file their payslips and tax returns to prove they can afford the watch if they want it back,” the source claimed.

So there’s evidence that the store’s celebrity customers broke laws.
