Raleigh, N.C. — Raleigh police are investigating a report of robbery and aggravated assault in downtown Raleigh over the weekend that left a man seriously injured.

The attack happened just after 2:30 a.m. Saturday morning in front of La Volta Restaurant, at 411 Fayetteville St., when, Mia Longo says, she put down her purse near her car to help her friend, Josh Mosley, hail a taxi.

That's when, she says, four clean-cut, well-dressed men, with short-cropped hair, grabbed her wallet from her purse, and, when Mosley tried to intervene, put him in a headlock and beat him in the head.

"I tried helping as much as I could," she said Tuesday. "I ran and tackled one of them, and they kept throwing me to the ground."

Mosley remembers nothing about the attack, only waking up unable to move his arms or legs.

"My forehead was split open. It's been glued back together. My nose was broken," Mosley said Tuesday. "I suffered what's called cervical spinal strain."

According to a police report, the four men got away with approximately $100 from Longo and $90 from Mosley, as well as his watch. The report describes the men as "preppy."

Police are reviewing surveillance video from nearby businesses and hotels but say they have no leads. They have not received any other reports of similar crimes in the area.

Anyone with information about the attack should contact the Raleigh Police Department at 919-996-3335 or Crime Stoppers at 919-834-4357.
