 UPDATE: Adrian Peterson's lawyer Rusty Hardin released the following statement: 
 
 "The allegation of another investigation into Adrian Peterson is simply not true. This is not a new allegation, it's one that is unsubstantiated and was shopped around to authorities in two states over a year ago and nothing came of it. An adult witness adamantly insists Adrian did nothing inappropriate with his son. There is no ongoing or new investigation." 
 
 HOUSTON -- New accusations against Adrian Peterson come from another mother who has another four-year-old son of Peterson, and also involve Peterson striking his boy as a form of discipline. 
 
 Peterson's attorney Rusty Hardin responded with the following statement: 
 
 The allegation of another investigation into Adrian Peterson is simply not true. This is not a new allegation, it's one that is unsubstantiated and was shopped around to authorities in two states over a year ago and nothing came of it. An adult witness adamantly insists Adrian did nothing inappropriate with his son. There is no ongoing or new investigation. 
 
 Earlier Monday, a top law enforcement official confirmed knowledge of the allegations by the mother of Peterson's son back in June 2013. Photos, which the KHOU I-Team obtained from a source, show a head wound to a boy identified as Peterson's four year old son. It is a wound that weeks later, left a scar above his right eye. 
 
 Sources claim it allegedly happened while the boy, who lives out of state, was visiting Peterson at his gated home in The Woodlands. 
 
 The source provided a string of text messages allegedly exchanged between the Peterson and the boy's mother. They contain numerous grammatical errors: 
 
 Mother : "What happened to his head? 
 
 Peterson: "Hit his head on the Carseat". 
 
 Mother "How does this happen, he got a whoopin in the car" 
 
 Peterson: "Yep" 
 
 Mother: "Why?' 
 
 Peterson: "I felt so bad. But he did it his self." 
 
 The text messages go on to show Peterson saying he was disciplining his son for cussing to a sibling. Also in the text messages, the mother asks "What did you hit him with?" 
 
 Peterson never answers directly but writes "be still n (and) take ya (your) whopping, he would have saved the scare (scar). "He's aight (all right)." 
 
 The exchange continued: 
 
 Mother: "I'm real sensitive about my baby and him being hit." 
 
 Peterson: "You tripping if you want him, come get him. I'm not about to be getting questioned down like you (you're) CPS." 
 
 Sources confirm to the I-Team that the mother did file a report with Child Protective Services, but CPS declined to discuss the its investigation. 
 
 Peterson's attorney Rusty Hardin said the woman is shopping around false allegations. Meantime, the website TMZ quotes sources close to the investigation, saying the CPS case went nowhere because the injuries were accidental and that the boy struck his head on a car seat. 
 
 Peterson's first court appearance is scheduled for Oct. 8.

 HOUSTON — Photos and text messages obtained by the I-Team reveal another incident in which Adrian Peterson is accused of injuring another son while disciplining the boy. 
 
 The 4-year-old is by a different mother than the alleged victim in the Montgomery County case, in which Peterson is charged with felony injury to a child. In that case, Peterson admits to repeatedly striking the boy with a tree branch or "switch," but has maintained he did not intend to harm the child, and was using his judgment as a parent to discipline his son.

 The latest incident allegedly occurred last June, while the boy, who lives out of state, was visiting Peterson at his gated home in Spring. A photo, allegedly texted by Peterson to the boy's mother, shows a head wound to the boy covered by two bandages. Other photos, allegedly taken weeks later, reveal a scar over his right eye. 
 
 The text messages also describe an exchange about what happened. They contain numerous misspellings and shorthand: 
 
 Mother: "What happened to his head?" 
 
 Peterson: "Hit his head on the Carseat." 
 
 Mother: "How does that happen, he got a whoopin in the car." 
 
 Peterson: "Yep." 
 
 Mother: "Why?" 
 
 Peterson: "I felt so bad. But he did it his self." 
 
 The text messages go on to show Peterson saying he was disciplining his son for cussing to a sibling. 
 
 "It's absolutely criminal," said Randy Burton, a former chief prosecutor of family crimes in Harris County, and founder of the advocacy group Justice for Children. "You break the skin, you have bleeding, much less permanent scars, that is a crime." 
 
 But no charges were ever filed. Sources confirm the mother filed a report with Child Protective Services, but the outcome of any CPS investigation is unclear. 
 
 So is the method of the delivering the wound, according to the text messages. 
 
 Mother: "What did you hit him with?" 
 
 Peter never directly answered, but later replied: "Be still n take ya whooping he would have saved the scare (scar). He aight (all right)" 
 
 "This is very damaging information," Burton said. 
 
 Damaging, Burton said, because prosecutors in Montgomery County can use it as evidence in the felony case against Peterson. 
 
 "To prove intent, that it was not an accident, and to show that it was a course of conduct," Burton said. "It wasn't a one-off." 
 
 Peterson's attorney Rusty Hardin said that Peterson had done nothing wrong. 
 
 "The allegation of another investigation into Adrian Peterson is simply not true," Hardin said in a statement. "This is not a new allegation, it's one that is unsubstantiated and was shopped around to authorities in two states over a year ago and nothing came of it. An adult witness adamantly insists Adrian did nothing inappropriate with his son. There is no ongoing or new investigation." 
 
 The Vikings said they already were aware of the allegation. 
 
 "As part of the information we have gathered throughout this process, we were made aware of an allegation from 2013 in which authorities took no action against Adrian," the team said in a statement. "We will defer any further questions to Adrian's attorney Rusty Hardin."
– Adrian Peterson was accused of beating and injuring another of his sons to discipline him last June, but the football star was never charged in the alleged incident, according to reports. KHOU has obtained text messages between Peterson and the boy's mother—a different woman from the mother involved in Peterson's current abuse case. "Hit his head on the Carseat," Peterson apparently explains in one text, after reportedly sending a photo of the boy's bandaged forehead to the mother. But when the mother asks if her son "got a whoopin in the car," Peterson replies, "Yep." Later, he says the son was in trouble for using foul language. "Be still n take ya whooping he would have saved the scare (scar)," Peterson texted the mother. KHOU sources say the mother did file a report with Child Protective Services. According to TMZ sources, however, the investigation into the incident "went nowhere"; they say the boy had indeed hit his head on a car seat while he was being disciplined. Says Peterson's lawyer, per KHOU: This is not a new allegation; it's one that is unsubstantiated and was shopped around to authorities in two states over a year ago and nothing came of it. An adult witness adamantly insists Adrian did nothing inappropriate with his son. There is no ongoing or new investigation.
