Police made two arrests at Tynecastle on Saturday after Motherwell substitute Christian Mbulu was allegedly the subject of racist abuse. Police Scotland received footage which shows a group of supporters in the main stand, during Hearts' 1-0 win, shouting comments at the 22-year-old as he warmed up. Motherwell boss Stephen Robinson told BBC Scotland the act was 'an absolute disgrace' and added: 'I've just seen the video of it. 'I thought this was 2018 but that was the dark ages and dinosaur stuff. For a player to have to take that kind of stuff is disgusting. 'They should not be anywhere near football. There is no place for that in any walk of life. No walk of life should accept that in modern society.' Hearts released a statement pledging to implement stadium bans for the culprits. 'The club is aware of an incident of alleged racism during the second half of today's match against Motherwell and is cooperating fully with Police Scotland on the matter,' it read. 'Heart of Midlothian abhors racism and all forms of abuse, and the individuals in question will receive indefinite bans from Tynecastle Park.' Last month, a group of Hearts fans were heard chanting in support of far-right activist Tommy Robinson during their 2-0 loss in Paisley to St Mirren.
