Roosters to investigate alleged lewd behaviour by Pearce

Updated: 

Sydney Roosters have confirmed they will conduct an internal investigation after co-captain Mitchell Pearce allegedly engaged in lewd behaviour involving a dog.

Video footage emerged on Wednesday, appearing to show a drunken Pearce simulating a sexual act with the animal.

In the clip, which is said to have been recorded at an Australia Day party, Pearce is also accused of urinating on a sofa before being told to leave the property.

A statement from Pearce's club read: "The Sydney Roosters are aware of an incident involving Mitchell Pearce.

"The club has advised the NRL's Integrity Unit. The club will conduct an internal investigation and will be making no further comment at this time."

The NRL also released a statement on the matter, with a spokesman adding: "The Integrity Unit will work with the Roosters to ensure the matter is dealt with appropriately."

In addition to being a key figure for the Roosters, Pearce has represented New South Wales in State of Origin.

He was fined $20,000 by the Roosters in 2014 following an incident on a night out.

In 2010, Joel Monaghan left Canberra Raiders after admitting to simulating a sexual act with a dog, while Cronulla Sharks sacked Todd Carney in 2014 after a lewd image of the former NSW playmaker emerged online.
