A SECTION of Villa Park was evacuated after a fan suffered a cardiac arrest at half-time during Aston Villa's Europa Conference League defeat to Olympiacos.
An announcement was made as police rushed up to attend to the incident, with hundreds of fans moving to give emergency services and stewards access.
It said: "Could all supporters clear Holte Lower L2 and make sure the gangways are clear."
TNT Sports confirmed a fan, believed to be a man, had suffered a cardiac arrest and was being taken out to an ambulance by paramedics, who were applauded by both sets of fans.
The start of the second half was delayed by several minutes, before play resumed.

There was no update on the condition of the fan last night, although some reports claimed they were conscious as they were taken away.
TNT Sports reporter Becky Ives joined the broadcast from pitchside, and said: "Unfortunately right on the stroke of half-time the medical emergency happened. I was down the tunnel and the emergency services moved very quickly."
Villa, who were being watched by avid fan Prince William, trailed 2-1 at half-time when the medical emergency occurred, before they ended up losing 4-2 in a huge blow to their Europa Conference League hopes.
