Scottish FA chief executive Stewart Regan says a full investigation will be carried out with Police Scotland in the wake of "contemptible behaviour" after the Scottish Cup final.

After the final whistle was blown, thousands of Hibernian supporters invaded the pitch with Rangers officials claiming several players and staff were attacked following Hibs' 3-2 victory.

Speaking to the media after the match, Regan said the Scottish Football Association was "appalled by the scenes of disorder and the contemptible behaviour" and that a full probe would carried out along with Police Scotland.

He added: "The Scottish FA is appalled by the scenes of disorder on the field immediately after full-time and at the contemptible behaviour that ensued. What should have been an historic, memorable Scottish Cup final will now, sadly, be remembered for all the wrong reasons.

"Police Scotland and the stadium management initiated a Crisis Liaison Group as soon as the disorder began and we thank them for containing the situation as quickly as possible.

"The Scottish FA, along with Police Scotland and the stadium management have initiated a full investigation into the scenes that unfolded to understand how such a volume of supporters were able to enter the field."

A Rangers statement read: "Rangers Football Club is shocked at the disgraceful behaviour of Hibs fans at full time.

"Rangers players and staff were assaulted by these fans, who invaded the pitch and in the interests of their safety could not return to the pitch for their medal presentation.

"There can be no place for the violent behaviour witnessed at the end of the final and Rangers fully expect the Scottish Football Association and Police Scotland to launch an investigation to find out where security measures failed and why.

"The club would like to commend Rangers fans for the restraint they showed under severe provocation."

Police Scotland said the scenes on the pitch were "inexcusable."

Chief superintendent Kenny MacDonald confirmed they will work with the Scottish FA and added: "Following today's Scottish Cup Final at Hampden, a significant number of fans ran onto the pitch following the final whistle.

"Officers, including the Force's mounted branch, responded and brought the matter under control as quickly as possible. We understand that feelings run high at these events and fans want to celebrate their team's win, however the reckless behaviour of fans entering the pitch is totally unacceptable and inexcusable. This created a significant safety issue.

"This action led to an outbreak of disorder between rival fans on the pitch. A dedicated investigation team is being set up to identify those who have carried out these acts of disorder and violence."
