Following on from the pre-season friendly and the infamous chant "If Shola scores, we're on the pitch" . it was Sammy Ameobi's turn for notoriety. VIDEO OF THE TROUBLE: http://www.youtube.com/watch?v=0yWM__kgvwg Sure enough, Sammy hit the back of the net at Darlington last night . and the shit hit the fan. Supporters invaded the pitch during United's pre-season friendly and three fans were arrested and another escorted from the ground. The Magpies vowed to take "the strongest possible action" against fans responsible for causing a 10-minute delay in the match as celebrations of Ameobi's 55th-minute goal turned ugly. The match looked in danger of being called off as scenes turned violent at The Darlington Arena and, although calm was eventually restored, the guilty parties can expect repercussions. Derek Llambias: "On behalf of everyone at Newcastle United FC, we wholly condemn the behaviour of a number of our supporters who invaded the pitch during the second half of the club's friendly against Darlington this evening (July 15). "The club will be seeking to obtain footage of the disorder from Darlington FC and the police and will be taking the strongest possible action against those individuals responsible for the shameful behaviour. "This behaviour is not typical of the vast majority of our fans, however this incident gives a poor impression of Newcastle United and its loyal supporters." Durham Police confirmed three visiting Newcastle fans were arrested for "pitch incursion" and another was escorted from the ground. Manager Alan Pardew intervened to try to calm fans down and appeal for them to clear the pitch. Some of the 9,000-plus crowd thought the match had been abandoned but the referee managed to restart the game after the playing surface was cleared. There was also an isolated outbreak of fighting between fans during the match. A force spokeswoman said: "There has been a crowd of more than 9,700, which is significantly more than expected based on ticket sales. "Everything was peaceful until Newcastle scored their second goal and a pitch incursion occurred which was high spirited but not violent. "A further pitch incursion of around 20 to 30 people followed - a Newcastle supporter being escorted from the ground and three Newcastle supporters were arrested for pitch incursion."
