American golfer Billy Horschel helped restrain a protestor at The Open after the Just Stop Oil group attempted to interrupt the event at Royal Liverpool.
Protestors reached the edge of the green on the 17th hole and threw orange confetti, which had to be blown away by course staff.
Horschel was seen trying to assist stewards in removing one female protestor from the course.
The tee box at the 15th hole was also targeted during the 151st Championship.
Play was not halted by any of the protests but the R&A said it was aware of two incidents and was investigating. One protestor got away.

Merseyside Police confirmed four people have been arrested.
