The PSNI says it is investigating a "security breach" in relation to the US President's Northern Ireland visit.
Joe Biden landed in Belfast International Airport last night, at around 9pm, and was met by Prime Minister Rishi Sunak. He travelled into the city centre late on Tuesday night, ahead of a full day of engagements on Wednesday.
Hours before President Biden is due to speak at Belfast's Ulster University Campus, BBC's Nolan Show reported that it's been shown a document linked to the visit. The document, reportedly found on the street, was marked "PSNI and sensitive".
