The Rugby Football Union has launched an investigation into alleged homophobic and racial abuse aimed at referee Nigel Owens at Twickenham on the weekend.

It is claimed that a section of England supporters subjected the Welsh official, who revealed he was gay in 2007, to derogatory chants during the Red Rose's 24-21 defeat at the hands of New Zealand.

An official complaint was made by one fan to a national newspaper, which in turn sparked the RFU into taking action.

"The RFU condemns all forms of discrimination and aims to ensure that all people, irrespective of their age, gender, ability, race, religion, ethnic origin, creed, colour, nationality, social status or sexual orientation, have a genuine and equal opportunity to enjoy rugby union in whatever form, on or off the pitch, at all levels and in all roles," a statement from the governing body read.

"We take any allegations of any abuse very seriously and are investigating this matter."

Speaking to The Telegraph, Owens added: "If someone has gone to the trouble to send a letter to the paper and say that this was disgusting and the behaviour was totally out of order, then I would think what they shouted was pretty bad and if that is the case then these people should be banned from the game.

"They need to be told that some behaviour is not acceptable, that crossing the line of what is humour and banter is a fine line but if you cross it then you have to put up with the consequences."

The investigation is ongoing.
