Two suspected drug dealers are under arrest for allegedly beheading a man who owed them money.
The two men were arrested on Thursday. Baja state prosecutors said the men confessed to killing 30-year old Rames Mendoza.
Mendoza was reported missing last week and his severed head was found Monday hanging from a bridge in Tijuana.
Cartel-style violence largely abated in Tijuana after the January 2010 capture of Teodoro "El Teo" Garcia Simental, one of two reputed crime bosses allegedly caught up in a bloody turf war in the city across from San Diego.
But Tijuana has seen a series of beheadings, bridge hangings and shootings since President Felipe Calderon visited in October and touted the city as a success story in his four-year-old drug war.
