A 7-year-old boy thwarted armed robbers who broke into his home by locking himself into a bathroom and calling 911, KTLA reports.

The three suspects, who were holding the boy's parents and younger sister at gunpoint Tuesday morning, apparently did not know until too late that the boy was in the house, Norwalk sheriff's deputies said, according to the Los Angeles TV station.

"There's some guy who's going to kill my mom and dad," he tells the 911 operator. "Bring cops. A lot of them ... And bring soldiers, too."

The gunmen apparently overheard the conversation and broke into the bathroom, as indicated by the boy's scream as they took the phone.

But they fled quickly when he told them he had called 911, KTLA says.
