Philadelphia police on Tuesday released the audio clips from the radio calls surrounding the controversial arrest Thursday of two black men at a Starbucks in center city Philly. The arrests sparked protests and a call for a social media boycott of the national chain.

Philadelphia's police commissioner on Saturday defended officers who arrested two black men at a Starbucks, prompting accusations of racism on social media and an apology from the company.

Videos posted online show officers handcuffing the men in the downtown establishment on Thursday. A white man in the video is heard saying he was meeting with the men and calls the arrest "ridiculous."

Commissioner Richard Ross said Starbucks employees called 911 to say the men were trespassing. He said officers were told that the men had come in and asked to use the restroom but were denied because they hadn't bought anything, as he said is company policy. He said they then refused to leave.

Also on Tuesday, Starbucks said it plans to close more than 8,000 U.S. stores for several hours next month to conduct racial-bias training for its nearly 175,000 workers. The announcement comes after the arrests sparked protests and calls for a boycott on social media. Starbucks says the stores and corporate offices will be closed on the afternoon of May 29.
