San Antonio police and the Bexar County sheriff's officials surrounded and searched the Bexar County Courthouse building early Friday morning after reports that someone tried to burglarize the building.
But by noon on Friday, sheriff's officials officials were backing off of that initial report.
"At this time, we are not sure that there was an actual burglary in progress," said BCSO spokesman Paul Berry. "We are reviewing all the surveillance tapes, and we're just not sure exactly what has happened."
The incident in question happened around 2:40 a.m. on Friday when an off-duty deputy who was working security for the contractor doing restoration work at the courthouse reported seeing someone inside who shouldn't be there.
Initially, reports indicated that the deputy confronted a man who dropped some sort of construction equipment then ran off.
At that point, sheriff's officials, along with San Antonio police officers and a K-9 unit searched the building.
Early reports also indicated that there was video showing someone crawling into the courthouse through a basement window that was open for construction.
"I'm not sure if the video actually shows that," Berry said late Friday morning. "We do have video of somebody who was inside the building. They could have gotten in through a window."
Deputies detained and questioned two people who were in the area and matched descriptions of the person or people believed to have broken in, but those people were released.
There were several people inside the courthouse at the time because it is under construction overnight.
Berry said all doors are secured but it's possible someone inside could let in someone who shouldn't be there.
The sheriff's office is still reviewing surveillance video and trying to get to the bottom of what happened.
