LONDON (AFP) - The Rugby Football Union announced Wednesday that it will probe allegations of player misconduct during England's disastrous two-Test tour to New Zealand.

The investigation will be conducted by the RFU's disciplinary officer Jeff Blackett, who intends to reveal his findings as soon as possible.

Blackett's probe will run separately from the police investigations taking place in New Zealand involving allegations of serious sexual assault against four unnamed England players.

The decision was made after the RFU Management Board's regular monthly meeting, during which the RFU Elite Rugby Director, Rob Andrew, gave a detailed report on the tour down under.

"The Board were concerned at the damage to the game's reputation as a result of the allegations made regarding the behaviour of four of the 32-strong touring party after the first test match in Auckland," a RFU statement read.

England were beaten 37-20 in the opening Test by the All Blacks yet a section of the squad later embarked on a drinking session at a nightclub, which concluded with girls returning to the team hotel.

"The Board noted that no formal complaint had yet been made to the Auckland police, that the players deny the allegations and that they have the full support of the England squad and team management in this respect," it said.

The RFU added: "In the age of celebrity, England players must always be aware of their position and the dangers that may exist for them at all times."
