Initial reports regarding the Chad Johnson arrest suggested that Johnson told police his head inadvertently struck the head of his wife during an argument in their car.

The official police report, obtained by TMZ, indicates that Johnson actually told police his wife applied the head butt to him.

The arresting officer, Christopher Epps, explained in the report that Johnson’s wife, the former Evelyn Lozada, told Epps that she “returned home . . . from shopping and began taking the items she purchased into the house. While taking out the groceries, [she] located a Wal-Greens [sic] receipt in the vehicle’s trunk with a charge for a box of condoms.”

The report then states that Johnson and his wife sat inside the car, parked directly in front of their house. “They began talking about the sales receipt and their marriage,” Epps wrote. “As they were talking Johnson became upset and without [Evelyn’s] permission grabbed her and head butted her on the forehead causing a laceration. Johnson began screaming and [she] attempted to calm Johnson down. He began screaming, ‘I don’t give a f–k! I don’t give a f–k about my career!’ [She] then fled on foot to a neighbor’s house to get away from Johnson.”

Epps also wrote that the laceration on Johnson’s wife’s forehead is “approximately” three inches long. At a local hospital, her injury was photographed, and she provided a tape-recorded statement.

Johnson confirmed to Epps that they were arguing about the sales receipt. But Johnson claimed his wife initiated physical contact with him.

Johnson has been released on bail, and he has been ordered to stay away from his wife. The Dolphins have not permanently ordered him to stay away from the team facility.

Yet.
