A Lafayette man seriously injured in a fight in which police say he was trying to defend his sister.

The woman's husband, Ray Chambers, of a King Street Address, in Linwood, has been charged with aggravated assault and battery.

Lafayette Police say Changers had been "roughing up" his wife, and she called her brother, Bo Frazier, for help. The two men got into a fight and Chambers is alleged to have hit Frazier on the head with a baseball bat.  

Frazier was airlifted by Lifeforce to Erlanger for treatment.
