POLICE were today investigating after a racist tweet was posted about Dons defender Shay Logan.

The message was circulated on Twitter before Aberdeen FC’s 4-0 defeat to Celtic at the weekend.

However, police only received a complaint about the tweet late last night.

Today, a Police Scotland spokeswoman confirmed a probe had been launched.

She said: “A complaint has been received in the last 24 hours and our inquiries are ongoing.”

The tweet was made in relation to Celtic winger Aleksandar Tonev being found guilty by the SFA for racially abusing Logan in a previous meeting in September last year.

Tonev was banned for seven games, despite insisting he was innocent.

This is the third tweet which has been under police investigation this week, following Sunday’s match.

Yesterday, an Aberdeen recruitment worker was suspended by his company for allegedly sending a sectarian message to Hoops striker Leigh Griffiths.

On Monday, a 19-year-old was charged by police in Aberdeen accused of posting an offensive message about Celtic fan Jay Beatty, who won SPFL Goal of the Month for January and has Down’s Syndrome.
