Former GWS football boss Graeme Allan told a staff member to delete an email from Lachie Whitfield's girlfriend raising alarms about the player's alleged drug use and behaviour.

Whitfield's girlfriend had emailed a player welfare worker at the club, Brett Hand, expressing concern at her boyfriend's behaviour, possible drug use and hiding from drug testers.

Hand is understood to have approached Allan about the email and was told by Allan that he would deal with it and to delete the email. He is understood to have told Hand the girlfriend was erratic, difficult and he would handle the matter.

Hand deleted the email but is not accused of any wrong doing as he was following instructions from a manager and believed the matter was being dealt with.
