Police have said a protester put himself in "a lot of danger" by flying a motorised paraglider over the Turnberry resort during Donald Trump's visit.

Trump's arrival at Turnberry on Friday was met with a huge breach of security, when a protester flew over the building, with a banner billowing behind him.

The banner read "Trump, well below par."

The protest took place while airspace around the golf resort was closed off by police and the Civil Aviation Authority.

Police Scotland have launched a criminal investigation into the matter.

Assistant Chief Constable Mark Williams said: "There is now an active criminal inquiry into the breach of the air exclusion zone around Turnberry yesterday evening.

"A powered parachute was flown in front of the hotel."

He said police were aware Greenpeace had organised the protest and officers were now investigating the individual who was in the paraglider.

ACC Williams continued: "I would stress that the individual who flew the powered parachute put himself in a lot of danger by entering the air exclusion zone.

"Whilst we understand and respect protest will take place, the air exclusion zone is there for a reason.

"It's there to protect the President and it's there to protect people who wish to protest in such a way."

ACC Williams said he was "delighted" that protests in Glasgow had gone peacefully and officers would facilitate further demonstrations on Saturday.

Ben Stewart, of Greenpeace, said: "He's truly the worst President ever.

"He doesn't want to see any protesters so we buzzed him last night when he arrived with a big banner saying 'Trump, you're well below par.'"
