Houston police were called to Discovery Green at about 9:23 p.m. Saturday after receiving reports of a "teenager takeover" at the downtown park, authorities said.

Officers arriving at the area found an estimated 500 to 600 juveniles, along with various adults, gathered at Discovery Green.

Additional Houston Police Department resources responded to help with crowd control, with officers focused on preventing the group from dispersing into other locations - particularly the FIFA Fan Fest, police said.
