A man was stabbed in the chest by his son outside an Aberdeen shopping center Wednesday afternoon, Aberdeen police said.

Officers were called at 3:47 p.m. to the Aberdeen Shopping Plaza, off Route 40, where they found a man with a stab wound to his chest. He was taken to Johns Hopkins Bayview Medical Center, but his condition was not known Wednesday night, police said.
