Tyreek Hill is under investigation for a battery incident in which a juvenile is listed as the victim.

Hill’s fiancee, Crystal Espinal, is listed under “others involved.”

“The club is aware of the investigation involving Tyreek Hill,” the Chiefs said in a statement to The Star. “We’re in the process of gathering information and have been in contact with the league and local authorities. We’ll have no further comment at this time.”

The source said that the incident was against the couple’s son, resulting in a broken arm.

Hill has a history of domestic violence. He reportedly punched and choked Espinal, who was then eight weeks pregnant with their son, on Dec. 11, 2014. He was arrested and dismissed from the Oklahoma State football team. Hill pleaded guilty to domestic assault and battery by strangulation in August 2015. He received three years probation. The Chiefs selected Hill in the fifth round of the 2016 NFL Draft.
