LOS ANGELES — A co-founder of the popular frozen yogurt chain Pinkberry has been found guilty of beating a homeless man with a tire iron in Los Angeles.

City News Service reports that 49-year-old Young Lee was convicted Friday of assault with a deadly weapon. Lee, who is no longer affiliated with Pinkberry, was taken into custody and is scheduled to be sentenced Jan. 14.

Prosecutors said Lee confronted the homeless man in June 2011 because Lee thought the transient had disrespected his wife by showing a sexually explicit tattoo.

The homeless man was struck twice in the head and suffered a broken arm before witnesses stopped the attack.
