No charges will be brought against four men arrested after images of Donald Trump and convicted sex offender Jeffrey Epstein were projected on to Windsor Castle, Thames Valley Police has said.

The men - a 60-year-old from East Sussex, a 36-year-old and a 50-year-old both from London, and a 37-year-old from Kent - were arrested in September over the incident during the US president's state visit.

They were arrested on suspicion of offences including malicious communications and public nuisance.

In an update on Wednesday, the force said no further action would be taken against them after an investigation concluded.

The president was friends with Epstein in the 1990s and early 2000s. Trump has never been officially accused of wrongdoing in connection with the deceased paedophile financier.
