Bendel Insurance will forfeit three points and three goals for assault on match officials during their 1-0 home loss to Kano Pillars last Saturday.
The Nigeria Premier Football League (NPFL) took the decision after receiving the report of the matchday 11 encounter played at the Samuel Ogbemudia Stadium, Benin City.
The club has also been fined N2 million for failing to provide adequate and effective security as well as failing to ensure proper conduct of their supporters during the game.
The Benin City club will pay another N1 million fine for misconduct capable of bringing the game to disrepute.
Bendel Insurance will further pay a fine of N250,000 each to the assaulted match officials, Adeniyi Adewale, Anuoluwapo Balogun and Sodiq Sonibare.
Insurance have 48 hours from the date of notice to appeal the sanctions.
