Dallas homicide investigators arrested a second juvenile Wednesday in connection with the death of a 19-year-old who was dragged by a Dallas Area Rapid Transit train.
Police said four to five boys between the ages of 12 and 14 attacked Octavius Lanier on the platform of the MLK Station at about 6:40 p.m. Tuesday, robbing him and pushing him into a moving train as it left the station.
Lanier was knocked into the side of the train and pinned between the train and the platform as it pulled away from the station, police said. Lanier was dragged several yards.
A juvenile arrested Tuesday night was charged Wednesday morning with capital murder. The charge was elevated because of the assault, robbery and slaying occurred at the same time, officials said.
A second juvenile was arrested Wednesday.
Police said they are not releasing the names of the suspects becaues they are underage.
Witnesses told Dallas police that a group of boys was seen harassing Lanier before he exited the train at the MLK Station.

The latest news from around North Texas.
DART spokesman Mark Ball said DART typically doesn't have much of a problem with group or mob crime. But a rider said he has seen kids harassing riders before on trains and had previously chalked it up to kids just being kids.
Ball said investigators were fortunate that cameras being installed at all DART stations were already put in at the MLK Station. Otherwise, video evidence from Tuesday night might not have existed, he said.
DART hopes to have all of the cameras installed by the end of the year.
Dallas homicide detectives continue to investigate the case. Four to five juveniles are possibly involved.
