The Ukrainian league was shocked on Saturday when a fan leapt from the crowd and attempted to choke a linesman.
The incident happened during Chernomorets Odessa's 1-1 draw against Metalist Kharkiv.
The referee and his assistant went to the technical area to talk to Chernomorets coach Roman Grigorchuk, who was upset by the award of a corner against his side.
The assailant then sprinted onto the pitch and grabbed the linesman round the neck.
Stewards and riot police quickly wrestled the man to the floor, but he continued to struggle violently as he was led off the pitch.
Despite the disturbing episode, play continued and the match was completed normally.
It ended 1-1 after Metalist substitute Willian scored a late equaliser with a 'scorpion kick' reminiscent of Colombian goalkeeper Rene Higuita, who pulled off the trick against England at Wembley.
"It was a beautiful goal - quick thinking - there was nothing else I could do," Willian told Globo Esporte.
"The goalkeeper saved the ball and I was a bit ahead of it, so I allowed my body to go forward and shot with my heal. It was similar to the save of Higuita."
