The disorder at the Scottish Cup final shows that it is not "an appropriate time" to scrap the Offensive behaviour Act, an SNP MSP has said.

Glasgow Shettleston MSP John Mason has lodged a motion before the Scottish Parliament which states the "scenes" after the cup final show the need to keep in place the Offensive Behaviour Act and the ban on the consumption of alcohol at football grounds.

Police Scotland have so far made 11 arrests for "minor offences" in connection with the Hampden pitch invasion following the end of Saturday's Scottish Cup Final between Hibs and Rangers.

Fans from both sides clashed on the pitch and Rangers said in a statement that players and staff were "physically and verbally assaulted".

In recent weeks Scottish Labour MSP James Kelly has stated that he will bring forward a private members bill to repeal the legislation.

Speaking on Monday, Kelly said: "I think if you look at some of the scenes on Saturday, the charges coming out from that are likely to use assault or breach of the peace legislation. They won't use the Offensive Behaviour at Football Act. That act is irrelevant in terms of dealing with the scenes that happened after Saturday's game.

"What's clearly needed now is for the fans, police and the clubs all to work together. This legislation breeds distrust and division amongst the fans and the police. And therefore I will be pressing right ahead with my plans to repeal the Offensive Behaviour at Football Act."

The MSP tweeted on Tuesday, following Mason's motion, that the Act was "inadequate" to deal with the cup final disorder and that he will be "pressing ahead" with his private members' bill which will aim to repeal the legislation.

The motion states: "That the Parliament notes the excellent Scottish Cup Final at Hampden Park on 21 May 2016 but shares the widely felt disappointment at the scenes following the game; understands that football can be a great opportunity for fans to let off steam but that there have to be limits as to what behaviour is acceptable; notes calls to change the law in relation to football, including repealing the ban on alcohol and relaxing the rules on offensive behaviour, and, in light of the recent situation, considers that this would not be an appropriate time to relax the law in either of these areas."

All opposition parties pledged in their Holyrood election manifestos to scrap the Offensive Behaviour Act.

As the SNP hold a minority of seats in Parliament opposition parties could use their parliamentary majority to scrap or change the law.

Liberal Democrat MSP Liam McArthur said that the idea that scrapping the legilsation would lead to more pitch invasions like Saturday's was "absurd".

McArthur said:"No one wants to see crowd trouble at any football match and it is right that the police are looking closely at events at Hampden over the weekend. But it is slightly absurd to suggest that scrapping the flawed OBFA would make violent pitch invasions more likely.

"The fact remains that this was a poorly drafted piece of legislation that should be scrapped."

Scottish Greens' Justice spokesperson John Finnie MSP called the motion "unhelpful".

Finnie said: "This is an unhelpful intervention by John Mason as there are both police and SFA inquiries ongoing to establish what actually happened at Hampden. The police are to be commended for responding quickly to a serious situation. What led to the pitch invasion must be carefully examined. Jumping to conclusions with ill-considered parliamentary motions helps no one."

Justice secretary Michael Matheson said that Saturday's events "underline" the need to keep the ban on alcohol at football grounds in place.

Matheson said: "I think if anybody thought that reintroducing alcohol into Scottish football was a good idea, events of Saturday, I believe, just underline that it was not and I'm pleased that we stood our ground on that particular issue and opposed those parties in the Scottish Parliament who sought to try to change the legislation to allow alcohol to be reintroduced to grounds.

The Scottish Government said that the Offensive Behaviour Act "sends out a clear message" on "hate crime".

A spokesperson said: "A YouGov poll shows 80 per cent of Scots support the Offensive Behaviour Act - a view shared by the overwhelming majority of those in the sample who follow Scottish football.

"The Act sends out a clear message that Scotland will not tolerate any form of prejudice, discrimination or hate crime, and it gives police and prosecutors an additional tool to tackle this behaviour. Any move to repeal the Act would send entirely the wrong signal and would undermine progress in driving all forms of prejudice from the game.

"The vast majority of football supporters are well-behaved and simply wish to support their team and enjoy the game. The independent evaluation of the Act found that the legislation had an immediate impact and that offensive behaviour at football matches has decreased since the legislation was introduced. It also found that the clear majority of fans condemn abusive behaviour towards people's religious beliefs and found songs celebrating the loss of life or supporting terrorism offensive."
