Concerned about strange people running through their neighborhood at night, several Hidalgo residents invited a CBS 4 News reporter to stop by -- and witness the problem firsthand.
Graciela Perez said she's concerned about the people who attempt to sneak through her neighborhood every night.
Depending on the day, 30 to 50 people pass through the Hidalgo Viejo neighborhood, Perez said. Dogs start barking, waking many residents.
"We think they are undocumented immigrants and we're scared," Perez said. "Honestly, we're scared because of what's going on in Mexico."
CBS 4 News reporter Imelda Mejia spent Monday night and early Tuesday morning at Perez's home.
At about 4 a.m., dogs started barking. Through the window, CBS 4 News cameras captured several men running down Levee Avenue.
Someone called the Hidalgo Police Department, which dispatched an officer to patrol the area.
Border Patrol agents, who typically park near the border wall, weren't spotted until 8 a.m.
"It is alarming because we used to see families, women with their children, fleeing from the violence over there," said Hidalgo resident Karla Cantu, adding later: "They would come to work, but now it's only men that are coming across."
CBS 4 News called Border Patrol about Perez's concerns. The agency released a statement saying it would review the situation and notify field supervisors about the activity.
