According to police, officers were dispatched to the area of 6th and Turner streets in Allentown, Pennsylvania at about 3:40 a.m. for a report of a man waving a firearm.
When officers arrived, police said 27-year-old Dominick Hogans ran before he brandished a firearm and fired at officers.
Allentown police returned fire and hit Hogans.
Police said officers rendered aid on the scene and Hogans was taken to an area hospital where he later died.
The investigation is ongoing and an autopsy is scheduled for Tuesday.
This is the second fatal officer-involved shooting in Allentown this year.
The first happened in February, and in that case, the district attorney ruled the officer's actions were justified.
