Arradondo, called as a prosecution witness at Chauvin's murder trial, said the use of force against Floyd was reasonable during the "first few seconds" of his May 25, 2020 arrest but it should have ended quickly, AFP reported.
"It is contrary to our training to indefinitely place your knee on a prone, handcuffed individual for an indefinite length of time," the police chief of the Minnesota city said.
"That in no way, shape or form is anything that is by policy," he said. "It is not part of our training and it is certainly not part of our ethics or our values.
"Once Mr. Floyd had stopped resisting, and certainly once he was in distress and trying to verbalize that, that should have stopped," Arradondo said.
The 45-year-old Chauvin, who is white, was seen in a video taken by a bystander kneeling on the neck of a handcuffed Floyd for more than nine minutes as the 46-year-old African-American man complained repeatedly that he "can't breathe".
Arradondo, 54, Minneapolis's first Black police chief, fired Chauvin and the three other officers involved in the arrest that led to Floyd's death the day after the incident.
The harrowing video of Floyd's arrest touched off protests against racial injustice and police brutality in the United States and around the world.
Chauvin has pleaded not guilty to charges of murder and manslaughter.
Another senior Minneapolis police officer, Inspector Katie Blackwell, testified on Monday about the training in the use of force that Chauvin and other officers received.
Blackwell, who headed the police training unit, was shown a picture of Chauvin kneeling on Floyd's neck and asked if that was an approved neck restraint.
"I don't know that kind of improvised position that is," she said. "It's not what we train."
Eric Nelson, Chauvin's attorney, introduced video at one point that he said showed Chauvin's knee on Floyd's shoulder blade and not on his neck.
Prosecutors countered that the video depicted the moment when paramedics arrived and Chauvin had removed his knee from Floyd's neck to get up.
Also testifying on Monday was the doctor who treated Floyd when he was brought to the emergency room at the Hennepin County Medical Center.
Bradford Wankhede Langenfeld said Floyd was in cardiac arrest when he arrived and 30 minutes of efforts to revive him were unsuccessful.
He said a lack of oxygen was the most likely reason Floyd's heart had stopped beating.
Prosecutors are seeking to prove that Floyd's death was due to asphyxiation while Chauvin's defense attorney claims it was due to illegal drugs in his system.
