FBI Houston and Harris County Sheriff’s Office reported that they were conducting “law enforcement activity” in north Houston related to the attack in New Orleans.
The agencies secured a perimeter near the intersection of Hugh Road and Crescent Peak Drive, and they are asking people to avoid the area.
FBI Houston personnel and specialized teams will be on-site for several hours, according to a statement
I don't know if this is where the suspect lives, but looking at Google Maps, there is a mosque about 0.3 miles away from the named intersection.
