POLICE have launched an investigation into the offensive chants by Celtic fans over the murdered soldier Lee Rigby as reports surfaced naming and shaming those responsible.

Footage uploaded on social media shows Hoops supporters seen and heard in the streets of Sunderland singing: "F... Lee Rigby, he won't be f...ing drumming anymore. Will he f..."

The sick song concerned the 25-year-old Royal Regiment of Fusiliers soldier, who was murdered by terrorists in May 2013.

The clip is believed to have been filmed on Saturday before the match between Celtic and Sunderland at the Stadium of Light.

Some have forwarded details of who they believe took part to Police Scotland and now Northumbria Police have confirmed they are looking into the complaints.

Tommy Robinson, the founder of the far-right English Defence League, who was in Sunderland wearing a Glasgow Rangers shirt - the arch rivals of Celtic - later offered a £1000 reward on social media to "anyone who identifies any of these scum bags".

A Northumbria Police source said: "We’re aware of the chants that were made and are looking into these to see if any criminal offences took place and will take necessary action."

The Herald:

Celtic on Wednesday released a statement saying it is "appalled" by the behaviour and was prepared to take "the strongest possible action" against any of the perpetrators involved once they are identified.

The club said: "Such behaviour, in no way, represents Celtic Football Club or our supporters."

The mother of Lee Rigby, Lyn, called on the club to “denounce these scum wearing their team’s shirt”.

She has said she has not “stopped crying” since the video surfaced ahead of the friendly Dafabet Cup clash.

The Herald:

She said: "As you can imagine we have been hurt, traumatised and deeply shocked to see the hate filled video directed at Lee by fans of Glasgow Celtic.

"It has been heartbreaking for his sisters who still feel the pain of his loss every day.

"Football fans the world over have supported our family and continue to do so."

In the build-up to the match, riot police were forced to intervene as fighting broke out in North Bridge Street in the city.

Lee Rigby, a drummer and machine-gunner in the Royal Regiment of Fusiliers, was murdered, in what was claimed to be an Islamist terrorist-inspired attack near his army barracks in London in May 2013.

Extremist Michael Adebowale, 25, was jailed for 45 years and accomplice Michael Adebolajo, 32, was jailed for life for killing the off-duty soldier.

The pair knocked him down with a car before hacking him to death with a meat cleaver and knives.
