New York ? Former Enron CEO Jeffrey Skilling was taken to a hospital early Friday after several people called police saying he was pulling on their clothes and accusing them of being FBI agents, a police source familiar with the incident said.

Police took Skilling to the hospital after finding him at 4 a.m. at the corner of Park Avenue and East 73rd Street and determining he might be an “emotionally disturbed person,” the source said.

Police did not charge Skilling with a crime. They took him to New York Presbyterian Hospital for observation. Hospital officials would only say that Skilling had been discharged from the hospital on Friday.

Messages left for Skilling’s lawyers, Bruce Hiler and Dan Petrocelli, were not immediately returned.

Skilling has been charged with fraud, insider trading and other crimes in the energy trader’s colossal collapse.
