The reports are coming after that city was hit with a series of three package bombs, believed to be related, this month that killed two people and wounded several others.
According to the Austin-Travis County EMS, officials are responding Sunday night to an incident on Eagle Feather Drive.
It was initially identified as possibly two separate incidents in the same general area, but first responders later clarified it appears to be a single incident.
It was unclear if it is believed to be related to the earlier explosions.

A reward for information in three earlier package bombings has risen to $115,000.
Anthony House, 39, died from his injuries in a package bombing at his home on March 2.
On March 12, 17-year-old Draylen Mason was killed when he and his mother opened a package found outside their home. His mother was left injured in the attack.
So far no one is in custody in those earlier bombings and the motive remains unclear.
They do believe the packages were delivered as some sort of message.
Later that day across town, a 75-year-old woman was injured when she also found a strange package on her porch.
