Fans staged protest during pro-am tournament

Desmond escorted off St Andrews course by security

Celtic’s principal shareholder Dermot Desmond had tennis balls thrown towards him during his visit to the Alfred Dunhill Links golf tournament at St Andrews in a protest from fans.

The 76-year-old – who has been criticised by supporters for an apparent lack of progress on the pitch – was taking part in the pro-am event on Saturday when the disruption happened on the green of the 15th hole.
