SAN DIEGO - 10News is learning more about what the owners of a downtown bar are calling a "vicious assault" on an employee by a San Diego Chargers player in the Gaslamp District.
The owners of barleymash say Chargers linebacker Thomas Keiser attacked a man Sunday evening.
Keiser was arrested and booked on suspicion of misdemeanor battery. He is no longer in custody, police said.
barleymash owners told 10News that Keiser attacked a male employee from behind and they have surveillance video to prove it. The video is being reviewed by police.
They said in a statement, "barleymash has proof that this was, instead, an unprovoked, vicious assault by Mr. Keiser on a barleymash employee."
After one of the individuals in Keiser's small party was asked to leave, Keiser re-entered the restaurant.
"He inconspicuously followed an employee to an area outside the restaurant's office, where he sat and waited for several minutes," the owners said in a statement. "When the employee emerged from the office, Mr. Keiser ambushed and brutally assaulted him."
10News was told barleymash security held Keiser until police arrived and arrested him.
Keiser is known for his stellar plays on the field. His most recent was two weeks ago as he intercepted a pass thrown by Peyton Manning in the Chargers' win against the Denver Broncos.
The Chargers say they are aware of the situation and will let the legal process run its course.
