NEW ORLEANS -- Police say they have arrested a second suspect in the shooting that injured 20 people at a parade on Mother's Day.
Police Chief Ronal Serpas identified the second suspect as 24-year-old Shawn Scott, brother of 19-year-old Akein Scott.
Akein Scott was arrested Wednesday night.
Serpas says Shawn Scott was arrested Thursday.
Both face 20 counts of attempted second-degree murder.
Akein Scott appeared before a magistrate judge Thursday.
His bond was set at $10 million.
Serpas says four additional people have been arrested and charged with harboring the suspects.
Serpas says investigators believe the Scotts worked together in the shooting.
