PROVIDENCE, R.I. (AP) _ Police say a man is in custody after another man trying to stop a fight was stabbed to death in Providence.
Providence Police Maj. David Lapatin said the unidentified 21-year-old man died shortly after he and his 26-year-old brother were stabbed Sunday morning in a confrontation with two other men.
Lapatin told The Providence Journal that officers who witnessed the assault grabbed an attacker as he tried to flee. The unidentified 30-year-old man is in custody, but has not been charged.
The brothers' identities were not released Sunday morning as officials notify their family.
