The Swedish prime minister has disputed Donald Trump’s claim over the treatment of a detained American rapper following a phone call between the two leaders.

Platinum-selling artist A$AP Rocky was arrested in Sweden in early July on suspicion of assault following a street brawl.

Mr Trump tweeted on Saturday that he had spoken to Prime Minister Stefan Lofven offering to personally vouch for his bail. Mr Trump said the Swedish PM assured him that the rapper would be treated fairly.

“Just had a very good call with @SwedishPM Stefan Löfven who assured me that American citizen A$AP Rocky will be treated fairly," Mr Trump said in a post on Twitter.

"Likewise, I assured him that A$AP was not a flight risk and offered to personally vouch for his bail, or an alternative... Our teams will be talking further, and we agreed to speak again in the next 48 hours!"
