Shocking video released by the NYPD Wednesday shows a brutal gang assault in Queens in which two teenage girls were badly hurt outside a McDonald's after an argument that started on social media escalated, authorities say.

The suspects, all of them also teenage girls, repeatedly punched the 14- and 15-year-old victims, and at one point even used a stun gun on them during the attack just after 4 p.m. Monday in the parking lot of the fast-food restaurant on Springfield Boulevard in Queens Village, authorities said.

A backpack belonging to one of the victims was stolen during the attack, which had $50, an ID and $120 AirPods inside.

The victims suffered swelling and bruising to the head and body as a result of the attack, in addition to cuts and scrapes. They were treated for their injuries, and are expected to recover.

The suspects, a 14-year-old, a 16-year-old and a 17-year-old, were arrested and charged with harassment and second-degree assault. The 16-year-old also was charged with weapon possession, the stun gun allegedly used on the victims.
