A white security guard pleads not guilty after he pulled a gun on a Black police officer in uniform. 

Security guard Seth Eklund pulled a gun on Lucas County’s Sheriff's Deputy Alan Gaston. Eklund pleads not guilty to a charge of aggravated menacing. Monday is his first court appearance.  

According to ABC 13, Gaston entered the IRS office in full uniform with his badge and firearm visible to ask a question. 

The incident occurred on May 31 while Gaston was on duty. He says he stopped at the IRS office to ask for a phone number. The security guard commanded the deputy to put the firearm in his car, and Gaston refused. 

Video footage shows the security guard drew his gun on Gaston. Eklund points his gun at Gaston’s back and then follows him to the elevator. 

"Basically preparing myself to be shot at that moment. Bracing for a shot in my back," Gaston told ABC 13. 

He also said that in that moment he thought he was going to lose his life. "There's really no way to know how you're going to act when there's a gun pointed at you and when you think you're going to lose your life," said Gaston. 

The deputy is dealing with emotional and psychological trauma because of the event. He and his wife have filed a civil lawsuit against the security guard and the security guard company and are in pursuit of compensation. The deputy is currently on medical leave.
