A second suspect was arrested in connection with a videotape that shows him and another man teaching a 2- and 5-year-old how to smoke marijuana, according to the Fort Worth Star-Telegram.
Vanswan Polty, 18, of Fort Worth was arrested Friday and charged with two counts of injury to a child, a third-degree felony. He remained jailed Saturday on $150,000 bail, according to the paper.
Police arrested 17-year-old Demetris McCoy on Feb. 23 after finding the video which shows the two men giving marijuana cigarettes to McCoy's nephews.
The video shows two children being taught to smoke marijuana and the men encouraging them to "get high," police said. A man can be seen placing a marijuana cigarette into a baby's mouth and, in another part of the video, a different boy is shown smoking on his own.
In the video, the children are called "potheads" and asked if they "have the munchies," the Star-Telegram reported.
"The video contains disturbing images of the young children being badgered into smoking a marijuana cigar, commonly referred to as a 'blunt,"' according to a release from the Watauga Department of Public Safety.
The bail for McCoy, 17, was set at $150,000. He remained in jail Saturday, the paper reported.
Police found the video Feb. 22 while investigating McCoy and Polty in connection with some area burglaries. Polty also faces burglary charges.
The children have been in the custody of Child Protective Services since last week, a spokeswoman said.
