A man has been arrested after Rangers captain James Tavernier was confronted by a pitch invader during the match with Hibs at Easter Road on Friday night.
The defender was on the touchline preparing to take a throw-in when a fan, who appeared to come from the home end, ran up and kicked the ball away.
Tavernier reacted by pushing him away.
The pitch invader was eventually grabbed by security.
A Police Scotland spokesman confirmed that a 21-year-old man has been arrested in connection with the incident.
The incident happened right before half-time. During the break, a seat was then thrown onto the pitch.
The police spokesman added that inquiries were ongoing.
The incidents come after a report into stadium safety was published earlier this week.
The independent review of football policing in Scotland found inconsistencies in the way safety certification is managed across the country.
It said the safety of spectators was put at risk and there could have been a “critical safety incident” at any of the grounds if not for the intervention of “committed professionals”.
During Hibs’ Scottish Cup quarter-final defeat to Celtic last Saturday, a bottle was thrown onto the pitch as Hoops winger Scott Sinclair prepared to take a corner.
Club chief executive Leeann Dempster later admitted the stadium’s CCTV was unable to pinpoint the culprit.
