A teenager has been charged with making an offensive social media post aimed at Rangers striker Alfredo Morelos.

Police Scotland said on Monday they had been investigating complaints that the Colombian had suffered racial abuse in a video during Sunday's Old Firm game.

Morelos scored his first ever goal against Celtic in the 1-1 draw.

It comes days after team-mate Glen Kamara said he was racially abused by Slavia Prague's Ondrej Kudela.

A Police Scotland spokesperson said: "A 17-year-old male youth has been arrested and charged in connection with an offensive social media post during the Celtic v Rangers SPFL match on Sunday, 21 March 2021.

"A report will be sent to the Procurator Fiscal.

"He has been released on an undertaking and is due to appear at Dunfermline Sheriff Court on Thursday, 22 April 2021."

Kudela admitted swearing while covering his mouth during his side's Europa League win at Ibrox on Thursday but not the "disgusting accusation" of racism.

Because of the offensive nature of the alleged comments, the BBC is not reproducing them.

Sunday's match was the first meeting of the sides since Rangers clinched the Premiership title, with fans praised for staying away from Celtic Park following mass celebrations from Rangers fans upon their title success earlier this month.

On Monday, Slavia issued a statement claiming their fans had suffered online death threats in the fallout from Thursday's tie.

The matter has been escalated to Uefa, while the Czech side have contacted Police Scotland over an alleged "brutal attack" after the game.

"If the outcome warrants it, we will act," said Slavia. "We believe everything will be investigated and we will respect the decision."
