Cleveland Browns quarterback Johnny Manziel has been involved in another police incident. According to a report released in Fort Worth, Texas, Manziel’s ex-girlfriend Colleen Crowley said Manziel had struck her “several times” on Saturday night.

The alleged incident took place over a disagreement at the Zaza Hotel in Dallas. Police confirmed, “no criminal complaint” had been filed in the wake of the report.

Crowley told police Manziel had threatened, “shut up or I’ll kill us both” as he struck her and dragged her by the hair in the argument on Saturday. The pair reportedly then drove to her apartment in Fort Worth, during which time Manziel is alleged to have struck her again. Miss Crowley ran to a neighbour’s house to report the incident to police while Manziel left the scene on foot.

For his part, Manziel denied hitting anyone or threatening suicide. In an interview with TMZ Sports, he said: “it didn’t happen.” Fort Worth police had reported Miss Crowley as “increasingly uncooperative” during their interview with her, saying she proved unwilling to have photographs taken of her injuries.

Troubled NFL star Manziel will reportedly leave the Cleveland franchise in March, according to NFL Media. Browns executive vice president of football operations Sashi Brown said in a release on Monday: “We’ve been clear about expectations…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.”

Manziel has had a difficult year off the pitch, with controversy and personal problems besetting his career. He was involved in a similar incident with the same woman after a heated argument by a road in Avon, Ohio – again police were called.

The Browns fined him for non-appearance at a team medical earlier in the season, and after video emerged of the quarterback at a club in Austin the team benched him ahead of the Week 12 match with Baltimore.
