SAN DIEGO (CBS 8 / CNS) - Just hours after the San Diego Chargers clinched the last playoff spot in the AFC by beating the Kansas City Chiefs 27-24 in overtime, linebacker Thomas Keiser was arrested on a misdemeanor battery charge in the Gaslamp Quarter.
Keiser, 24, was arrested about 10:50 p.m. Sunday outside of Barleymash on Fifth Avenue. He and his father were reportedly asked to leave by security after his father had too much to drink.
The pair left willingly, but Keiser returned an hour later, looking for the restaurant's manager. Security footage seen by CBS News 8 shows Keiser waiting for the employee before knocking him to the ground and punching him several times.
The unidentified man suffered minor injuries and refused treatment by paramedics, according to police.
Keiser was booked on a misdemeanor battery charge and posted $8,000 in bail.
The Chargers issued a statement Monday night, saying: "We're aware of the issue involving Thomas. We'll continue to monitor the situation and let the legal process run its course."
On Tuesday afternoon, the owners of Barleymash released the following statement:
"The owners of Barleymash wish to respond to the mischaracterizations of the incident that occurred at their restaurant on December 29, 2013 involving San Diego Chargers player, Thomas Keiser. Media reports have stated that there was an 'altercation that eventually turned into a fight.' In fact, this was an unprovoked, vicious assault by Mr. Keiser on a Barleymash employee. Mr. Keiser and his party departed the restaurant after one of the individuals in his party was asked by the security staff to leave. Mr. Keiser subsequently 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. When the employee emerged from the office, Mr. Keiser ambushed and brutally assaulted him. Mr. Keiser ran, but was detained by security personnel until police arrived and arrested Mr. Keiser.
The owners are extremely upset about this incident as Barleymash is not the type of venue where incidents of this nature occur. Barleymash is a sports restaurant geared toward food, sports fans, and families. The owners and staff wish to stress their ongoing support of the San Diego Chargers organization."
Keiser was signed by the Chargers in May after playing two seasons with the Carolina Panthers. He was waived by the Chargers Aug. 31 when the team reduced its roster to the regular-season maximum of 53 and signed to the practice squad a day later.
Keiser was promoted to the active roster in October and appeared in 12 games, starting three, including Sunday's, making 20 tackles and one interception. His 4.5 sacks was third on the team and tops among linebackers.
