White Settlement police said a man called their department at about 3:14 p.m. Tuesday and said he was going to park in front of Lockheed Martin and block the entrance. Police said the man told them they might want to get a negotiator. He told police was laid off last week
Police said Fred Thompson, 62, barricaded himself outside the front gate in a minivan at 3:45 p.m. The vehicle had signs in the windows that said "danger" and "do not approach or bump this car."
Lockheed Martin activated its barriers to prevent him from entering, and police diverted traffic away.
Thompson told a White Settlement police negotiator that he wanted someone to listen to him, saying he was upset with Lockheed Martin, the union and workers at the plant because he believed was being picked on, police said.
Police said Thompson surrendered about 30 minutes before the time he had agreed on with police. Police said he had self-inflicted cuts to his wrists, ankles and neck. Officers moved in and moved him to the grass, where paramedics treated him.
The Fort Worth Fire Department's bomb squad searched Thompson's minivan but not find any explosives or weapons inside.
Police said Thompson was employed at Lockheed Martin from 2007 until July 2010.
White Settlement police said they are reviewing the incident and determining if charges will be filed.
