A video of Cricket Australia (CA) chief James Sutherland speaking about the David Warner bar-room brawl incident.

David Warner had allegedly punched Joe Root, for which he was dropped from Wednesday’s match against New Zealand and on Friday, Sutherland slammed the role of the Australian team in the damaging Warner punch-up incident, demanding they crack down on bad behaviour.

Warner was Thursday fined Aus $11,500 ($11,000) and suspended until the start of the Ashes series next month for punching England batsman Joe Root in a Birmingham bar during the ongoing Champions Trophy.

The 26-year-old told a London press conference he had apologised to Root and admitted he let down his teammates, family and Australian cricket fans.

The explosive opener will miss the rest of title-holders Australia's involvement in the Champions Trophy and their two warm-up matches ahead of the first Ashes Test against England in Nottingham on July 10.

Sutherland said he, along with Australian fans, was disappointed in the latest incident, the second involving Warner in three weeks after he was fined Aus $5,750 over an expletive-ridden Twitter tirade at two Australian journalists.

Sutherland said it reflected poorly on the values and behaviour of the team.
