A 55-year-old Northwest man died last week as a result of traumatic brain injuries sustained during a Sept. 24 robbery, according to the Metropolitan Police Department.

Tsegaye Gebrehiwot was assaulted and robbed at about 11 p.m. in the 5100 block of 2nd Street NW. He was admitted to a hospital about a month later due to complications resulting from the incident, and he remained in the hospital until his death on Nov. 13, police said last Wednesday.

Because an autopsy connected his death to the robbery, detectives are now investigating the case as a homicide.
