An employee who called the police to the downtown Philadelphia Starbucks where two black men were arrested last week is no longer working there, Starbucks said on Monday, as the company’s chief executive apologized for the “reprehensible” episode.

“We can confirm that she is no longer at that store,” a spokeswoman said, declining to name the employee or provide further details.

The chief executive, Kevin R. Johnson, said in an interview with ABC’s “Good Morning America” that what happened to the men was “wrong,” and that he wanted to meet with them personally to apologize.

“It’s my responsibility to understand what happened and what led to that, and ensure that we fix it,” Mr. Johnson said. He said that the company was reviewing its guidelines, which can differ among its 28,000 stores worldwide, and that it would invest in unconscious bias training.
