Police said they were called to the party for crowd control at 7:30 p.m., but the shooting took place around 9:30 p.m. A 22-year-old man and a 14-year-old boy were hit.One of the victims is in serious condition. The other is in stable condition.

Chris Brown has a concert at Toyota Center on Monday night.

Local hip hop artists Just Brittany and Trae were at the party, along with nationally known hip hop artists Meek Mill and Tyga, according to posts on Instagram.

“It could have been (done) better than that,” Jyrie Polk, who attended the party, said. “They could have waited until the birthday party was over.”

The Houston Police Department is looking for the shooter. Police said they know there were a lot of people who witnessed the shooting, but few people are talking.

KPRC 2 contacted Brown’s lawyer as well as his spokesperson for comment, but have not heard back
