Johnny Manziel’s ex-girlfriend told Fort Worth police that he struck her, forced her into a car and told her, “Shut up or I’ll kill us both.” The episode took place Saturday following an argument between the woman, Colleen Crowley, and the Cleveland Browns quarterback, and it led to authorities searching for him with a helicopter.

Citing a police report, the Associated Press reported that Crowley told authorities that Manziel was “aggressive” toward her after they met in a Dallas hotel. She claimed that he struck her several times while driving her back to her Fort Worth residence, although the police report noted that Crowley was “somewhat vague on the details of the assault.”

WFAA in Dallas provided more details. According to the TV station, Crowley met Manziel, with whom she broke up in December after two years of dating, following a night of bar-hopping. They argued about another woman, at which point Manziel led her, against her will, to a valet area.

From the WFFA report:

“I was crying and begged the valet, ‘Please don’t let him take me. I’m scared for my life!'” [Crowley] told police. The valet reportedly told her, “I don’t know what to do” and let Manziel leave with her. …
She claims she jumped out of the car and tried to hide from Manziel, but he found her in some nearby bushes.
“He grabbed me by my hair and threw me back into the car and got back in himself,” she reportedly told police. “He hit me with his open hand on my left ear for jumping out of the car. I realized immediately that I could not hear out of that ear, and I still cannot today, two days later.”
Crowley then reportedly hit Manziel several times, hoping to get out of the car, but, she told police, Manziel “threw me off of him” and she hit her head on the car window. She told police he would not give her her phone. …
While en route [to Fort Worth], she claims, she yelled at him, “I hate you!” He allegedly replied that “he was going to drop me off, take my car and go kill himself,” sources said.
She says she thought he was on drugs or maybe having a psychotic break. She told police she then began telling him she loved him.
She says at that time Manziel “started laughing” and then reportedly yelled at her to “shut up or I’ll kill us both.”

Crowley reportedly told police that, once she and Manziel were at her Fort Worth apartment, he continued to behave in an angry and violent manner. She eventually pulled a knife out of a drawer, at which point the quarterback fled on foot.

TMZ Sports reported that it reached Manziel by phone Thursday, and that he denied hitting Crowley, telling the website, “It didn’t happen.” According to TMZ, Manziel added, “I’m completely stable. I’m safe and secure.”

WFAA reached Manziel’s father, Paul, who told the station Thursday, “We’re trying to get our son better. We’re not there yet.”

Manziel’s two seasons in the NFL have been marked by numerous off-field incidents amid inconsistent, sparing play. He is expected to be released soon by the Browns, who issued this statement 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.”

Update: Authorities in Dallas and Fort Worth have closed their investigations, with no charges being filed against Manziel.
