An attempted robbery at a jewelry store in a South Texas mall sparked fears of an active shooter on Friday, but police later confirmed it was just the sound of smashing glass, not gunfire. McAllen, Texas, police confirmed they had taken five people into custody at the La Plaza Mall in connection with the attempted robbery. They said no one was injured and no shots were fired.

The sound of the glass being smashed apparently prompted enough concern earlier that the Hidalgo County Constable's office for Precinct 4 posted a message on its Facebook page urging people to avoid the shopping mall due to an "Active Shooter at the McAllen Plaza Mall."

About an hour later, the City of McAllen confirmed that police were investigating an attempted robbery and that seven suspects had been apprehended. There were "no injuries involved" the tweet said, citing information from the Hidalgo County Sheriff.

Statement from Chief Rodriguez:

We are investigating a robbery attempt at a jewelry store @LaPlazaMall. All known suspects are in custody. No injuries involved.

Reports of shots fired are attributed to smashing glass cases. #StayInformed — City of McAllen, TX (@CityofMcAllen) July 28, 2018

Officers from the McAllen Police Department and personnel from the Hidalgo County Sheriff's Office and the Texas Department of Public Safety responded to the emergency call, CBS Harlingen affiliate KGBT reports. The mall was reopened nearly an hour after the incident.
