Another update for you on the situation developing in Lexington, KY, where a MoveOn supporter was attacked and stomped on by Rand Paul supporters

Sherelle Roberts, a public information officer for the Lexington division of police tells TPM that investigators have made no arrests and filed no charges in the case. But because the incident was caught on camera, officers are optimistic that a breakthrough is imminent.

"I think we're probably going to come up with something later today," Roberts said, adding that tips have been coming in literally from around the country about who the suspects in the attack might be. "Because it was captured on video, we have a good idea what happened [and] at this point there doesn't seem to be anything to justify how this incident unfolded."

Though the victim of the attack, Lauren Valle, was interviewed by police on the scene for about 20 minutes, none of the suspects were questioned. Roberts explained the crowd was chaotic, and the perpetrators had disappeared into it by the time police arrived.

"We weren't able to make contact with them," she said. "There was a large crowd of more than 100 people gathered.... By the time the officers were able to get to the scene the incident was over."

MoveOn's political director Ilyse Hogue tells us that Valle suffered a concussion and sprains to her shoulder and arm as a result of the stomping. We'll continue to keep you updated as information unfolds.
