Police are investigating threats made against the wife of Premier League and Champions League referee Michael Oliver, who refereed Wednesday's European clash between Real Madrid and Juventus.
Oliver awarded Madrid a last-minute penalty at the Bernabeu after Medhi Benatia fouled Lucas Vasquez, and was met by fierce opposition from Juventus' players, most notably captain Gianluigi Buffon, who was sent off for his reaction.
Cristiano Ronaldo scored the penalty to put Los Blancos through to the semi finals, having previously trailed Juventus 3-0 on the night with the tie heading towards extra time at 3-3 on aggregate.
BBC Sport report that Oliver's wife Lucy, a Women's Super League referee who also officiates non-league men's fixtures, had her mobile phone number posted on social media after the game, leading to abusive messages.
