Police report detailing Johnny Manziel incident released

— -- Quarterback Johnny Manziel allegedly struck his ex-girlfriend several times during an incident at the Hotel ZaZa in downtown Dallas last Saturday, according to a police report released Thursday. 

The two eventually left the hotel and drove back to Fort Worth, when Manziel allegedly struck her several more times, according to the report. 

Manziel's ex-girlfriend alleged that he was acting "as if he were on some kind of drugs" but maintained that he was not intoxicated. 

According to a report from ABC affiliate WFAA in Dallas, Manziel told the woman to "shut up or I'll kill us both" after he forced her into the car before they drove to Fort Worth. 

Manziel, in an interview with TMZ Sports posted on its website later Thursday, said of the claims that he struck his ex-girlfriend: "It didn't happen." He also said, "I'm completely stable. I'm safe and secure."

A source told ESPN's Pat McManamon earlier this week that the Browns plan to release Manziel in March, the end result of his latest off-the-field incident. 

The Browns, in a statement, said Tuesday: "We've been clear about expectations for our players on and off the field. Johnny's continual involvement in incidents that run counter to those expectations undermines the hard work of his teammates and the reputation of our organization. His status with our team will be addressed when permitted by league rules. We will have no further comment at this time."
