No injuries were reported at that location.
The second incident reportedly took place around 11:33 p.m. in the 7500 block of Cold Springs Boulevard. Two men with handguns forced their way into an apartment home, then bound the hands of the three occupants inside.
The robbers reportedly took several items and were fleeing, but one of the victims freed himself, retrieved a weapon and fired upon them.
One person was reportedly kicked in the head while another was struck around the face, the release said.
No arrests have been made in these or six other incidents that were reported to police from four different apartment complexes.
The police department is encouraging apartment residents to park in well-lit areas, be vigilant and report suspicious activities and people.
The incidents are being investigated by the Fort Wayne Police Department and the Allen County Prosecutor's Office.
