Celtic clinched their record 56th Scottish league title on Saturday by defeating Hearts 3-1 at Celtic Park in Glasgow [1, 2, 3]. The victory was sealed with a stoppage-time goal from Callum Osmand in the 98th minute, marking the eighth minute of added time [1, 2, 3].

Hearts opened the scoring early through a Lawrence Shankland header. Celtic equalised with a penalty by Arne Engels just before half-time. Daizen Maeda then put Celtic ahead in the 87th minute, before Osmand’s late goal confirmed the win [1].

Following Osmand’s decisive strike, numerous Celtic fans invaded the pitch in celebration. The Scottish Professional Football League (SPFL) condemned the pitch invasion as "wholly unacceptable," warning of potential disciplinary action pending a match delegate report [1, 2, 3]. An SPFL spokesperson stated, "We utterly condemn the scenes which saw a number of Celtic supporters encroach onto the field of play... supporters entering the field of play in any circumstances is wholly unacceptable and puts those participating and working at a match at risk" [2]. Despite the disorder, the match was not abandoned or ended early, and the referee confirmed the game had concluded before the trophy presentation [1, 2, 3].

Hearts players and officials left Celtic Park quickly, citing a "menacing and threatening atmosphere" caused by the pitch invasions and fan disorder [1, 2, 3]. The club released a statement describing "serious physical and verbal abuse towards our players and staff, both on the pitch and elsewhere," adding they are working with Police Scotland on investigations and expect strong action from football authorities [2].

Police Scotland responded to the post-match disorder by making several arrests. They also confirmed two officers were injured during the chaotic celebrations in Glasgow [2, 3].

The SPFL praised referee Don Robertson and his officials for maintaining composure throughout the dramatic match [1, 2, 3].

Police Scotland and football authorities will continue investigations into the incidents as they await the match delegate's report on the disorder at Celtic Park on May 16.
