An employee at the Riverside Post Office in Fort Worth held several of his co-workers at gunpoint Monday morning.
Police said 27-year-old Jason Silmon walked into the office on Retta Street with a handgun. He demanded that everyone get on the ground.
There were about 11 people in the office at the time and police said everyone complied. No one was hurt.
Police still aren't sure what motivated Silmon, but they said he put the gun down after just a few minutes and waited for officers to arrive.
He was arrested and charged with aggravated assault.
Robert Silmon, the suspect's father, said he was stunned when he found out his son had threatened his co-workers.
Robert said his son had worked for the post office for about eight years and was a good employee who had earned pay raises. But he said his son told him Friday he was having a "beef" with some of his fellow workers.
"I couldn't understand that that's not in his character and he's a good kid he don't bother anybody he's not a violent kid, I don't understand what happened," Silmon said.
