LOS ANGELES (Reuters) - A co-founder of the Pinkberry frozen yogurt chain who was convicted last year of beating a homeless man with a tire iron at a Los Angeles freeway offramp was sentenced on Friday to seven years in prison, prosecutors said.

Young Lee, a South Korean kick boxer-turned-architect who parted ways with Pinkberry in 2010, was found guilty in November 2013 of assault with a deadly weapon in the 2011 attack.
