ANGERED by the actions of Mike Tyson's entourage during their first news conference leading up to his WBC heavyweight title defence, Frank Bruno questioned whether Tyson learned anything while serving a 3 1/2 year prison sentence for rape.

"I thought prison was supposed to wise you up and make you a better man," said Bruno, who arrived in Las Vegas last Saturday from the Canary Islands where he had been training for six weeks. "He's getting worse, to be honest, both in the ring and out of the ring."

Bruno, who lost to Tyson on a fifth round knockout when the two first met seven years ago, was clearly irked after being heckled by members of Tyson's entourage during the news conference.

He refrained from getting involved in a shouting match with the entourage, but later criticised Tyson for his group's actions.

"The way these people go on is not good for boxing," said Bruno.

Bruno was the only one doing much talking, with Tyson making little effort to answer even the most basic questions before bringing the news conference to an abrupt close by getting up to leave.
