Arkansas Razorbacks football recruit Catrell Wallace has been arrested on second-degree sexual assault and tampering charges, according to the Benton (Arkansas) Police Department. 

Wallace, 18, turned himself in to police Monday at the Saline County jail. According to the police, an alleged sexual encounter between Wallace and a 12-year-old occurred during the early morning hours of Jan. 1. 

"Although it appears to have been a consensual encounter, BNPD detectives were able to determine that Wallace had reason to believe the victim was underage at the time of the crime," police said in a statement.
