Three Delaware teenagers involved in videotaped assaults of a mentally disabled man have been sentenced to probation and house arrest, followed by placement in a secure juvenile facility.

The teens were sentenced Monday after each pleaded guilty to a single felony count of crime against a vulnerable adult.

The boys, two 15-year-olds and a 14-year-old, were sentenced to probation and house arrest for the rest of the school year, followed by summer placement at a juvenile facility.

The defendants were charged with offensive touching, assault of a vulnerable adult, and conspiracy. Prosecutors later added hate-crime charges, which were dropped along with other charges following the guilty pleas.

Videos posted online showed the 27-year-old victim being body-slammed to the ground, stomped on and kicked, and repeatedly punched in the head.
