At least three people were arrested at a rally in Philadelphia, Tuesday. Protesters took to the streets following the fatal shooting of a Black man by police the day before.
27-year-old Walter Wallace was shot as officers responded to a report of a person with a weapon in the Cobbs Creek neighbourhood.
Wallace was allegedly armed with a knife. According to the officers, he was shot several times when he advanced towards them.
The man's father said that his son was on medication as he struggled with mental health issues.
