Ms. Athens, 41, is the main anchor for two outlets, KTBY and KYUR, which broadcast online as Your Alaska Link. Bill Fielder, the station owner, said the video Ms. Athens posted had not been approved. He has demanded that she remove references to the news outlets.
“We had no knowledge of it in advance of her posting it,” Mr. Fielder said.
Ms. Athens was arrested on Friday after a physical altercation with her boss at the station, according to local news reports, not long after her video was posted to Facebook. She was charged with misdemeanor assault, criminal mischief and disorderly conduct and released over the weekend on bail.
Mr. Fielder declined to discuss what led up to the arrest but said that Ms. Athens was no longer with the company, effective Monday.
Mr. Berkowitz, a former Alaska state representative who served eight years as minority leader, ran unsuccessfully for Congress in 2008 against longtime Representative Don Young and for governor in 2010. He was elected mayor in 2015.
Mr. Berkowitz was re-elected in 2018 by a wide margin. But in recent weeks, he has faced upheaval from some residents over the city’s efforts to control the coronavirus, including a mask mandate, capacity limitations at restaurants and prohibitions against large gatherings. Alaska has recorded some of its highest coronavirus numbers in recent days.
Under the city’s code, the chair of the Anchorage Assembly is in line to take over duties as mayor after Mr. Berkowitz’s departure. That position is currently held by Felix Rivera, but it is possible the Assembly could vote to reorganize to place someone else in the position. The city may then have a special election, or wait until the new mayoral election scheduled for April. Mr. Berkowitz was not able to seek re-election because of term limits.
The Assembly said in a statement before Mr. Berkowitz’s resignation that it had been informed on Monday of the “improper and distasteful actions taken by our mayor.” It said the authorities had found no evidence of illegal activity on the part of the mayor but noted his admission of a “consensual yet inappropriate” relationship with Ms. Athens.
“We are disappointed and disheartened by this news,” it said.
