This is the terrifying moment a woman and baby were carjacked by a gang of killers.

The dramatic crime was caught on security footage, which shows the four armed crooks bail out of a Mazda and hauling the woman and her infant niece out of their Kia minivan at gunpoint in Houston on Monday, according to the Houston Press.

The men had just completed a drive-by — fatally gunning down Sam Johnson, 53, and injuring Walter Fields, 22, the paper reports.

But their car got stuck in a gutter during the getaway, the footage shows — so they swarm the nearby minivan, ripping the aunt out and onto the ground with her niece’s car seat in her hands.

While that’s happening, one of the brutes fires again back at Johnson and Fields.

The woman and little girl were unharmed and police have since arrested one of the men –Mertroy Harris, 27, who has been charged with murder, the Houston Press reports.
