The former Ultimate Fighter season 27 competitor was taken into custody by the Coral Springs Police Department, facing charges of “robbery by sudden snatching,” as well as battery and criminal mischief. ESPN has since obtained records that show those charges stemmed from an apparent June 14th domestic violence incident, involving Pena’s girlfriend of the past year. Reports state that Pena accused his girlfriend of looking at other men on Instagram, after which police records say he took her cell phone and smashed it on the ground. That action appears to be the basis of the robbery charge, which carries a potential felony classification.
