Denver Broncos' tight end Daniel Graham was arrested Friday on suspicion of criminal mischief and harassment after allegedly entering his ex-girlfriend's house without permission and damaging her bed. Arapahoe County sheriff's deputies arrested him after an argument Thursday afternoon, when Graham allegedly showed up at the woman's residence in the 5600 block of South Helena Court and the two quarreled about selling the house, according to a news release. He is the father of her son, the release said. When police responded to that call, the woman reported a previous incident when Graham allegedly entered the house without permission on Sunday. The woman told police she asked Graham "several times" to leave, but he refused. During the argument, police said, Graham struck a bedpost with his hand and damaged the bed.
