Detroit Lions cornerback Terrion Arnold turned himself in at Orient Road Jail in Tampa on Wednesday night and faces eight felony charges: four counts of robbery with a firearm or deadly weapon and four counts of kidnapping.
The Hillsborough County State Attorney's Office confirmed the charges carry a potential life sentence in prison.
Arnold is being held without bond and is due in court on Thursday at 1.30pm ET / 6.30pm BST, and the state attorney's office said it will file a pretrial detention motion arguing that Arnold should remain in custody until his trial.
The charges relate to an alleged robbery and kidnapping in Tampa in early February.
ESPN reports the incident followed Arnold telling police that more than $250,000 worth of property had been stolen from an Airbnb he was renting in Largo, Florida.
Per ESPN, the state attorney's office accused Arnold of "coordinating and directing the codefendants" to lure his personal driver and two associates to an apartment.
All three men were reportedly pistol-whipped and held at gunpoint, though investigators later determined they were not involved in the original theft.
A group chat was also identified by investigators, in which Arnold and co-defendant Boakai Hilton allegedly directed others during the assault.
Arnold's management pushed back firmly in a statement released shortly after the arrest.
The Lions said, "We are aware of the legal situation regarding Terrion Arnold. We will not comment at this time out of respect for the ongoing legal process."
The NFL released a statement saying, "We are aware of the matter and have been in contact with the club. We have no further comment at this time."
The state attorney for the 13th Judicial Circuit in Tampa posted her own statement on social media.
Six others had been arrested previously in connection with the same incident, according to ESPN.
Two of those, Arianna Del Valle and Jasmine Randazzo, agreed to plea deals in court on Wednesday, just hours before Arnold's arrest.

Arnold signed a four-year rookie deal worth $14.3 million, fully guaranteed, when Detroit took him 24th overall in the 2024 NFL Draft.
He's earned roughly $5.9 million across his first two seasons, per Over the Cap.
Around $3.6 million in prorated signing bonus money and more than $4 million in base salary were still owed over the final two years.
The Lions also hold a fifth-year option that would have been worth approximately another $14 million if exercised next offseason.
Dan Campbell had told Arnold he would need to earn his starting spot back in training camp, which isn't a ringing endorsement for a player entering year three.
Whether Detroit voids the remaining deal may depend on how this proceeds legally, and the NFL's personal conduct policy will come into play regardless of the court outcome.
