The investigation of an alleged assault on a liberal activist by supporters of Republican U.S. Senate nominee Rand Paul continued Wednesday as Lexington police worked to identify those involved.

"We're trying to look at the totality of the situation," said Lexington police spokeswoman Sherelle Roberts.

Roberts said police are trying to determine how others were involved in the incident and whether they should be charged.

She confirmed that police have contacted Mike Pezzano, a Lexington man who has been identified as one of at least two men who brought the activist to the ground outside the studios of Kentucky Educational Television on Monday night.

No charges have been filed against Pezzano, and Roberts couldn't say when or if any additional charges might come.

Efforts to reach Pezzano for comment were not successful, but he told WKYT-TV he does not condone the actions of Timothy Profitt, 53, of Bourbon County, who stepped on the head of MoveOn.org activist Lauren L. Valle, 23, as she tried to pull a political stunt.

Profitt, who said he was concerned the woman was trying to attack Paul and acted only to subdue her, faces a criminal summons that could lead to a fourth-degree assault charge.
