Kooij oversaw Sunday's Eredivisie clash between Twente and Ajax, with the winner overtaking Feyenoord as league leaders.
Ajax were up 2-1 when Kooij suddenly interrupted the match in the 77th minute. The moment was highly controversial.
Sofyan Amrabat received a pass and lost possession in his own penalty box, surrounded by three Twente players. As Amrabat lost the ball, Kooij stopped the match, signalling that VAR official Dennis Higler was in contact about a potential crucial penalty.
Higler was reviewing a potential handball by Twente striker Wout Weghorst just before the interruption. The former Netherlands international swatted the ball away during a corner, but was pushed in the back by Dies Janse, which was enough for Kooij not to give a penalty.
The interruption angered Twente players, staff, and fans, with Kooij on the receiving end of many complaints and endless booing.
Following the game, Kooij was heard complaining about Higler in the tunnels of the Grolsch Veste. According to De Telegraaf's Mike Verweij, Kooij was heard saying "f***ing VAR" after leaving the pitch amid loud whistles and boos.
Twente finished the game by grabbing a point in the dying seconds, with Weghorst converting from the spot in the 95th minute.
