HOBOKEN - Six Newark teenagers are behind bars after police say they beat and robbed four PATH train riders over the weekend.

Officials say the victims alerted the Port Authority Police Department to the incident at about 1 a.m. Sunday on a PATH train heading from New York to Hoboken.

All four victims, three men and one woman, were treated at Hoboken University Medical Center and released.

A Port Authority spokesman says the suspects are between the ages of 15 and 17 years old.

Investigators say they were arrested in the Hoboken terminal with one of the victim's wallets.

All six suspects were taken to Hudson County Juvenile Detention Center and have been charged with gang assault and robbery.

The latest juvenile attack comes on the heels of the death of 46-year-old Eric Santiago, who was allegedly killed last month by two 13-year-olds and a 14-year-old.
