It is understood a person won about $20,000 by obtaining the judges’ votes, which were supposed to be sent confidentially after being cast via StatEdge.
Bellamy was up against the Roosters’ Trent Robinson, Canberra’s Ricky Stuart, Parramatta’s Brad Arthur and the Sea Eagles’ Des Hasler, and was not considered the favourite to win one of the night’s biggest honours.
Bookmakers told the Herald in March that Bellamy was backed into as short as a $1.80 favourite to win the Dally M Coach of the Year despite opening at much longer odds.
The awards night had already been blighted when the NRL’s official Twitter account revealed Bellamy as the winner about 20 minutes before it was officially announced at the event.
Markets are shut down well in advance of the awards ceremony starting, with the gaffe not thought to have contributed to the abnormal bets.
“Today, officers attached to the organised Casino and Racing Investigations Unit, executed search warrants as part of on an ongoing investigation into reported betting activity, surrounding an award for the NRL commission,” a statement from police read.
“Search warrants were conducted at two separate residents at Paddington and Waterloo and a business premises in Surry Hills.
“Investigators seized documents, electronic devices and computers. Inquiries are continuing under Strike Force Mirrabei. As investigations are ongoing, no further information is available.”
