Hearts have banned two supporters after Motherwell player Christian Mbulu was allegedly racially abused during Saturday's Scottish Premiership clash at Tynecastle.

Defender Mbulu, who was an unused substitute in the game, was allegedly targeted while warming up on the touchline.

Police Scotland announced on Saturday that two people had been arrested after game, which Hearts won 1-0.

Hearts, who have said they are "cooperating fully" with police, announced on Sunday they were taking action.

Owner Ann Budge told BBC Scotland: ""This behaviour will not be tolerated.

"The individuals involved have already been identified and have received immediate and indefinite bans.

"I'm so very disappointed that instead of being able to enjoy a good victory and staying at the top end of the table I'm having to comment on the entirely unacceptable behaviour of a minority of supporters."

A police spokesman said: "Police Scotland can confirm that two subjects were arrested at the Hearts v Motherwell match."

Motherwell manager Stephen Robinson called the incident an "absolute disgrace".

He said: "I thought this was 2018 but that was the dark ages and dinosaur stuff for a player to have to deal with that kind of stuff. It is disgusting."
