A Logan man has been sentenced to a year in jail, after attacking his brother -- with a knife -- because he was angry about a Facebook posting.

Cache County authorities say, Sergio Arce, 20, went to his brother's home -- along with some friends -- after reading the social network posting.

There, police say, he stabbed his brother several times.  The victim was hospitalized with a collapsed lung.

Two other men still face charges in the attack.
