Police in Bulgaria have arrested more than 120 people in a small southern village following several days of ethnic riots.

The violence erupted Friday in Katunitsa, after a 19-year old teenager was struck and killed by a mini-bus driver linked to to a local Roma leader. More than 500 angry residents gathered in front of the Roma leader's home, hurling stones and setting his home on fire.

A 16-year-old boy collapsed during the protest and later died in the hospital of heart failure. Five others were injured.
