BATON ROUGE, La. (AP) - A Louisiana woman who authorities say stabbed her brother and attacked an EMS worker has been arrested.

WBRZ-TV reports 27-year-old Tiah Bradley was arrested Sunday and charged with attempted second-degree murder, battery of emergency room personnel and battery of a police officer.

The East Baton Rouge Sheriff's Office said in a report that Bradley and her brother got into a fight in which they exchanged punches. When the victim walked away, Bradley came behind him and stabbed him in the neck and torso. Deputies believe a 5-inch switch blade was used in the attack.

Authorities say Bradley also punched an EMS worker and kicked a deputy as he tried to restrain her.

Both siblings were transported to the hospital for treatment. It's unclear if Bradley has a lawyer.
