Houston police say it is not an active shooter situation, and initially said a male suspect set off firecrackers inside the mall, alarming patrons and sending them into a panic. But in an update on twitter, HPD said there were actually no fireworks discharged.
During a press conference, Harris County Precinct 5 Constable Ted Heap said surveillance video shows the suspect at 3:12 p.m. going up the escalator to the movie theatre. A few minutes later, the suspect was seen wearing a red half-mask. He took the escalators down to the food court area, where he jumped on a table and declared he was going to kill himself.
"He had something in a bag, and that point he had thrown the bag. At this point we have chaos - people started fleeing. He actually exited out the south entrance and headed in this direction over here towards these apartment complexes," Heap said.

According to Houston police, they are investigating this as a terroristic threat.
At least two people were injured during the incident, police say.
"Two injuries that occurred, fairly minor one of them was a 16-year-old boy and his mother. They were taken to the hospital they got caught up in the mass hysteria of the exit. It appears we have a minor ankle or leg injury and the mother was stepped on a few times on her back as she was trying to help her son," said Houston police's Cheryl Victorian.
