It follows a serious of threats towards manager Neil Lennon, including bullets being posted to him and a bomb being sent. And at Hearts on Wednesday night he was attacked on the touchline by a home fan.

The men, aged 41 and 43, were detained on Thursday morning after officers raided a number of properties in Kilwinning, Ayrshire. Police later said they had been arrested and detained in police custody under the Explosive Substances Act (1883).
