Bangladesh, Oct. 27 -- More than a dozen people were arrested and more than 30 officers injured in protests stemming from the police shooting death of a Black man they say refused their orders to drop a knife in a confrontation captured on video, Philadelphia police said Tuesday.

The man, identified by city officials as Walter Wallace, 27, was shot before 4 p.m. Monday in an episode filmed by a bystander and posted on social media. Bystanders and neighbors complained that police fired excessive shots.

Wallace's father, Walter Wallace Sr., told The Philadelphia Inquirer that his son appeared to have been shot 10 times. He said his son was also a father, was on medication and struggled with his mental health.
