"Cricket Australia (CA) has today advised that David Warner has been reported for breaching CA's Code of Behaviour. Warner is alleged to have breached Rule 6: Unbecoming Behaviour, regarding comments posted on his twitter account," the CA said in a statement.
Rule 6 states that "players and officials must not at any time engage in behaviour unbecoming to a representative player or official that could (a) bring them or the game of cricket into disrepute or (b) be harmful to the interests of cricket...This rule applies at all times where the unbecoming behaviour involves the player being involved in public comment or comment to or in the media."
Warner attacked two noted Australian cricket writers on his twitter page after one of them wrote a piece critical of the IPL, which is currently mired in a spot-fixing scandal.
Warner, who plays for the Delhi Daredevils, launched a series of abusive tweets.
Warner called Craddock a Pr*** who writes s*** and also described the other columnist Malcolm Conn an old f***.
The explosive series of tweets was immediately noted by CA and they launched an inquiry into the matter.
