Saitama, Japan – Japan's Daiki Kameda defended his World Boxing Association (WBA) flyweight title on points against Romania's Silvio Olteanu.

In a split decision three judges scored it 116-112, 115-113 for Kameda, while the other counted it 110-118 for the challenger.

It was the 21-year-old Kameda's second defence of the title he won from Denkaosen Kaowichit of Thailand in February, stretching his record to 19 wins, including 11 KOs, against two defeats.

The 32-year-old Olteanu, ranked 14th in the WBA, has now 11wins, including five KOs, against four defeats.

Kameda is the second of three boxing brothers, all of whom have bad-boy images in the media and among boxing fans.

He was suspended from boxing for a year after his failed title bid against then World Boxing Commission flyweight champion Daisuke Naito in October 2007, for using dirty tactics including wrestling the veteran champion to the canvas.

Kameda's elder brother, Koki, was reprimanded by the Japan Boxing Commission for urging his brother to fight dirty.

Their father, Shiro Kameda, has been barred by the WBC from serving as a cornerman in its matches for abusing match officials and has been slapped with a life ban by Japan's boxing authority.
