A Tennessee woman who once appeared on a Bravo reality series is out on bond after being charged with aggravated assault at Walmart.

Diamond Tankard, 21, found herself in police custody on Saturday following allegations of aggravated assault using a weapon and theft. This event unfolded at a Walmart Supercenter in Antioch, a Nashville suburb. According to an arrest affidavit reviewed by Law&Crime, surveillance footage allegedly captured Tankard assaulting another woman in the checkout line. The victim’s grandmother, an eyewitness to the incident, reported to law enforcement that Tankard wielded a “sock filled with rocks” as a weapon during the attack.

Per the affidavit, officers were dispatched to the Walmart once the altercation was reported. The victim accused Tankard of approaching from behind while she was at the self-checkout, seizing her by the hair, and launching an assault, as described by police. Following this alleged attack, Tankard purportedly took the woman’s iPhone, valued at $1,500, along with her Louis Vuitton handbag, priced at $900.

Authorities noted that the victim sustained a visible cut on her forehead above her left eye. The grandmother reiterated to the police that Tankard allegedly used a “sock filled with rocks” to hit her granddaughter.

Tankard — who appeared on the Bravo reality show “Thicker Than Water” as a child — was identified after police viewed the store’s video footage, which was provided by the staff. She was reportedly seen “gathering items from the ground” that police believed were the stolen items. Tankard then ran from the store.

The woman was taken to the hospital and received stitches.

Tankard was arrested by the Metro Nashville Police Department and taken into custody on Saturday, charged with aggravated assault with a deadly weapon and theft. She posted $25,000 bond on the same day. Her next court date is scheduled for Aug. 22.
