Dallas Cowboys receiver Dez Bryant was arrested Monday after allegedly assaulting his mother, Angela, on Saturday, according to DeSoto, Texas, police captain Ron Smith. According to the incident report, Bryant became angry when his mother asked him to leave her home during an argument Saturday afternoon. Initially, at a Tuesday news conference, Smith said Bryant slapped his mother in the face, but the police report, which was released later Tuesday, clarified that Bryant allegedly grabbed her by her T-shirt and hair and "hit her across the face with his ball cap." Angela Bryant, whose T-shirt and bra were allegedly torn during the incident, indicated on a 911 call that this was not the first time she was assaulted by her son. "I can't keep letting him do this," said Angela Bryant, who made the call from the nearby home of family friend and adviser David Wells. "I can't keep letting him do me like this. I'm tired. I'm going to put an end to it today. I'm going to put an end to it today. I'm tired." Officers who responded to the 911 call from Bryant's mother did not observe any injuries, and she did not complain of pain at the time, according to the report. On Monday, after officers contacted Bryant's mother at her home, the report states that she said she had pain in her wrists, hands and arms. Officers observed swelling around her wrists at that time, according to the report. After being transported to the DeSoto police department, Angela Bryant, 37, provided a written statement detailing the alleged assault. According to the report, she stated Dez Bryant repeatedly struck her in the hands and wrists. Officers observed bruising on both arms. She also complained that her chest was sore from Bryant pushing her. After a warrant was issued for his arrest, Bryant turned himself in Monday and was booked without incident.
