Brazilian police to investigate football violence

Brazilian officials say they have ordered an investigation into the violence that broke out at the final of the Copa Sudamericana in Sao Paulo.
The Sao Paulo State Public Safety Department says witnesses, players and security personnel will be questioned, but did not provide further details.
Sao Paulo was awarded the title when Argentina's Tigre refused to take the field for the second half of Wednesday's second leg of the final. Sao Paulo was leading 2-0, with the first leg having ended scoreless.
Officials of the Argentine club said their players and staff were beaten by security officials in the dressing room area at halftime and guns were drawn.
