President Donald Trump had blamed "sick" vandals, and a former Olympian had been charged, but prosecutors now say contractors caused the damage.

US prosecutors have dropped charges against a former Olympian who had been accused of vandalising the Reflecting Pool in Washington DC, writing in court documents that the damage is now believed to be "the result of flawed installation by the contractor". President Donald Trump had previously blamed the damage on "sick, deranged" vandals. But a document filed by prosecutors in Washington DC on Friday says new information "strongly suggests that a rushed and botched installation" job overseen by the US Department of Interior led to the damage. David Hearn, a champion canoeist, had been facing a 10-year prison sentence if found guilty after his arrest last month. A piece of the new blue paint could be seen peeling off the bottom of the pool on Thursday In a statement, Hearn's lawyers accused the Trump administration of abuse of power, and said it "owes Mr Hearn an apology". Hearn previously told the BBC that he "didn't destroy, rip, tear, peel, or remove any part" of the paint in the pool. Asked by the BBC on Friday if he is planning legal action over the government missteps that led to the charges and false public accusations, he declined to comment. The document filed by US Attorney for Washington DC Jeanine Pirro blames contractors for rushing the paint installation process as part of Trump's efforts to beautify the city ahead of the country's 250th independence anniversary on 4 July.
